Difficult personalities: hard patterns in yourself — or someone you love

Maybe every relationship you've had has blown up the same way, and you're starting to wonder if the common factor is you. Or maybe you live with, work with, or grew up with someone whose moods, blow-ups or put-downs run the whole show — and you're worn down to the rims.

Either way, this page is for you. It's about what professionals call "personality disorders" — long-running patterns in how someone feels, relates and reacts that cause real damage, over and over. SANE estimates these patterns affect a meaningful slice of the population, and most people who have them never chose them — they're usually built out of genetics plus hard early experiences.

One ground rule before we start: nobody gets diagnosed from a webpage — not you, not your ex, not your old man. Only a qualified professional, after proper assessment, can do that. What you can do here is recognise patterns and learn what actually helps. That's worth a lot.

What's actually going on?

Your personality is your factory settings — the habits of feeling, thinking and reacting you run on autopilot. Everyone's settings have quirks. It becomes a clinical issue when the patterns are extreme, show up everywhere (not just with one annoying boss), go back years, and keep wrecking relationships, work or the person's own life.

You might have come across the term "Cluster B". Plain translation: it's a grouping clinicians use for the patterns that run hot — dramatic, intense, erratic. The main ones:

• Borderline patterns — emotions that go from zero to a hundred, terror of being left, relationships that swing between "you're perfect" and "you're dead to me", a shaky sense of who you are. Healthdirect has a solid plain-English overview.
• Narcissistic patterns — needing to be admired, taking criticism like a knife, struggling to genuinely care how others feel, using people to prop up a self-image that's more fragile than it looks.
• Antisocial patterns — disregarding rules and other people's rights, lying or manipulating without much guilt, a long trail of burnt bridges.

Three things worth knowing straight up:

• Traits sit on a spectrum. Everyone is a bit self-centred or a bit clingy sometimes — especially under stress. Having some traits is human. A disorder is when the pattern is severe, everywhere, and causing serious harm.
• These patterns usually grow out of pain. Especially borderline patterns, which are strongly linked to tough or unsafe childhoods. That's not an excuse for harmful behaviour — but it does mean the person isn't simply "evil", and it means change is possible.
• Treatment works better than most people think. Borderline patterns in particular respond well to specialised talking therapies — DBT (dialectical behaviour therapy — practical skills for handling huge emotions) has solid evidence behind it. "Personality disorder" does not mean "hopeless case". Not even close.

Signs to look for

Two honest checklists — one for looking in the mirror, one for looking across the kitchen table.

Patterns in yourself

• Every close relationship follows the same script and ends the same way
• Your anger goes from nothing to everything in seconds, and the clean-up costs you people
• Being left — or even imagining it — feels unbearable, and you'll do almost anything to stop it
• Criticism, even mild, feels like an attack, and you hit back hard
• You notice you charm, pressure or guilt people into what you want — and feel little about it afterwards
• More than one person who cares about you has said a version of the same hard thing
• Underneath it all: emptiness, or not really knowing who you are

Worth knowing: in men, borderline patterns often get missed because they come out as anger, recklessness and heavy drinking rather than visible distress — so blokes get called "aggro" when what's underneath is pain.

Patterns in someone close to you

• You're walking on eggshells — their mood decides everyone's day
• You're idolised one week and torn down the next
• Apologies never quite happen; somehow everything ends up being your fault
• They punish closeness in others — your mates, your family slowly drop away
• You've stopped trusting your own read on things ("maybe I am the problem")
• You feel drained, anxious or flat in a way you didn't before this relationship

One caution, said with care: it's become fashionable to slap "narcissist" on every difficult ex. Sometimes a relationship just failed. Sometimes both people behaved badly. The label matters far less than the question that actually helps you: is this relationship harming me, and what am I going to do about it?

What to do right now

1. Swap the label for the pattern. "Is he a narcissist?" is a dead end — you can't diagnose him, and the internet definitely can't. "He puts me down in front of people and I've stopped seeing my mates" is something you can act on. Same goes inward: "Am I borderline?" matters less than "my anger is costing me people I love."
2. If a conflict is hot, take space — properly. Say "I need twenty minutes, I'm coming back" and leave the room. Walking out without a word inflames things; a named time-out de-escalates them. This works whether the big emotions are yours or theirs.
3. Step away from the 1am internet rabbit hole. Quiz sites and armchair-diagnosis videos will wind you up, not help you. Stick to the proper sources at the bottom of this page.
4. If you're being hurt, controlled or frightened at home, that's not a personality quirk — that's abuse. Call 1800RESPECT on 1800 737 732 (24/7, confidential, and yes — men can and do call). If you're in danger right now, call 000.
5. Talk it out with MensLine on 1300 78 99 78. Free, 24/7. Whether it's "I think I'm the problem" or "I'm at the end of my rope with someone" — they hear both, every single night.

What to do over time

If the hard patterns are yours:

• Give yourself credit for even asking. Most people with these patterns never look in the mirror. The fact you're reading this puts you ahead of the curve, and it's the single best predictor that things can change.
• See your GP and be straight. "The same problems keep happening in my relationships and I think some of it's me" is one of the most useful sentences a GP can hear. They can refer you for proper assessment and therapy — the pathway's in the next section.
• Commit to therapy like it's training. Therapies like DBT and schema therapy teach concrete skills — how to ride out a huge emotion without detonating, how to hear criticism without going to war. These patterns were learned over decades; unlearning takes months of reps, not two sessions. People genuinely do it.
• Tackle the grog alongside. Alcohol strips the brakes off every one of these patterns. Be honest with your GP about how much is going down.
• Repair where you can. A real apology — no "but" — to the people you've hurt won't fix everything, but it's how trust starts rebuilding.

If the patterns belong to someone in your life:

• Set boundaries and hold them. A boundary isn't a punishment or an ultimatum — it's a fence: "If you scream at me, I'll leave the room. I'll come back when it's calm." Calm, every time, no exceptions. Consistency is the whole trick.
• Stop arguing at the peak. You cannot reason with anyone — including yourself — mid-eruption. Disengage, revisit later or not at all.
• Don't take over their recovery. You can encourage someone to get help. You can't do their therapy for them, and burning yourself down won't light their way. Support, don't carry.
• Keep your own people and your own life. These relationships shrink your world if you let them. Mates, sport, work you care about — that's not selfish, it's ballast.
• Get your own support. Living alongside these patterns is genuinely hard on your mental health. A psychologist for you — see below — and SANE's free, moderated online forums for families and carers can be a lifeline.
• Know when distance is the answer. If someone refuses all help and keeps causing you harm, stepping right back — or out — can be the sane, healthy call. Especially where kids are involved: their safety comes first, full stop.

Where to get help

Same Australian pathway whether the patterns are yours or you're coping with someone else's.

Step 1 — Book a long appointment with your GP. Ask for a long appointment for a mental health chat. You won't shock them — relationship patterns, anger and burnout from a difficult home are bread-and-butter GP territory.

Step 2 — Ask about a Mental Health Treatment Plan. Your GP can set up a GP Mental Health Treatment Plan, which unlocks Medicare-rebated sessions with a psychologist — a set number of subsidised sessions each year (your GP can explain how many you can get), bulk-billed or partly rebated depending on the psychologist. If a formal assessment is on the cards, your GP can also refer you to a psychiatrist, with Medicare rebating part of the cost.

Step 3 — Find the right person. Your GP will usually suggest someone. You can also search via Medicare Mental Health or call them on 1800 595 212 (free). If it's your own patterns, ask for someone experienced with DBT or schema therapy. If it's about coping with someone else, say exactly that — plenty of psychologists specialise in it.

Any time, free, 24/7:

• MensLine Australia — 1300 78 99 78 — men's counselling, including relationship and family stuff
