NEVER try to self-diagnose.
I think that anyone concerned that they have BPD or any MH condition should get a referral to an NHS Psychiatrist.
This is my experience of BPD:
When i was seriously Depressed in Spring 2009 i finally asked my GP for that referral.
I saw 2 SHO-level Psychiatrists but i admit to not being very honest with them about how i truly felt, how paranoid i actually was, how obsessive & i never once said i was suicidal. I was scared to be honest with them in case i got sectioned.
I was sent for CBT to deal with the initial diagnoses of 'work-related stress & mild depression; but 16 appointments & 1 very frustrated therapist later i was referred to an NHS Consultant Psychologist linked with the Psychiatrist's team.
I started having appointments with the Cons Psychologist AND (finally) the Consultant Psychiatrist in late Spring 2010 & was given lots of tests to fill in.
I was still suicidal, self-harming, paranoid, & onto my 3rd (finally a bit more successful) Anti-Depressant (an SNRI).
I didn't know what the tests were for - i expected a diagnosis of Bipolar 2 maybe - because all i'd googled was 'types of Depression' & Bipolar 2 seemed to fit in slightly.
I was shocked to be told (in July 2010) that i had 'Borderline Personality Disorder' (aka 'Emotionally Unstable Personality Disorder'). Not quite so shocked to get a diagnosis of 'Chronic (Recurrent) Major Depressive Disorder' too.
I'd never heard of Borderline & spent months in denial questioning the diagnosis.
I had hour-long appointments with the Psychologist every 2 weeks for 18 months; she was frustrated too as she guessed i wasn't totally honest with her.
Plus I have Epilepsy & the meds (AEDs) i took for that were causing drowsiness & Memory Loss (basically Dementia-type side effects including muddled speech).
So at every session i would listen, take notes, then promptly forget where i put them or that i'd written them.
The Neurology team slowly took me off the horrible AEDs & slowly put me onto newer, safer AEDs. The drowsiness, tremor, constant hunger & 'Dementia'(!!!) side effects wore off thank god although i'm left with Memory Loss :(
The new Epilepsy meds are a revelation - i can think clearly again after over 7 years of feeling like i was 'swimming through treacle' or 'in a fog'. My eyes have lost the 'dreamy' look they had. The Epilepsy is not fully controlled due to the SNRI drug lowering my seizure threshold so i still get some Absence & Deja Vu seizures.
But the old meds also had a 'mood stabilising' effect. Unfortunately the BPD is much much worse now as i have more severe mood swings, suicidal thoughts, still self harm, get agitated & angry for no reason, switch in & out of paranoia, & transient psychosis :(
Not pleasant for me or my family (luckily i live alone though). I still have my job (but part time hours now); a family, colleagues & good friends who like me (because most of the time i'm horrible to myself not anyone else!).
I'm still obsessive & impulsive (overeating, undereating, overspending, meeting unsuitable men etc etc).
I am really really really sick of it all & keep wanting to give up on life but i know i'm lucky in a lot of ways so i just keep reminding myself of that.
The Psychologist is now aware of all my symptoms as i finally trusted her enough to start being honest with her.
She has referred me for DBT (Dialectical Behavioural Therapy) on the NHS - i've been assessed & accepted onto the (10 month!!!) waiting list. It's a therapy specifically for BPD patients - but you have to prove that you are 'bad enough' to need it; & that you are willing to work hard at the therapy to try & get well. I've heard DBT has a good success rate although my Psychologist isn't optimistic about my chance of recovery - she put it at 30% - that was when i was still badly affected by the old AEDs though.
My Psychiatrist feels i'm on enough medication unless the mood swings, paranoia & psychosis episodes get much worse. The truth is that most mood stabilisers & Anti-Psychotic drugs interract badly with the SNRI & with my Epilepsy meds; or they may lower my seizure threshold more.
I do accept my diagnosis but i do still question it when i get paranoid.
Now i'm on the DBT waiting list i only see the Psychologist once a month but see the Psychiatrist more often (8 weekly approx).
Also i can phone the Duty CPN or CMHT Crisis Team anytime i feel unwell - & i'm lucky to have an understanding & helpful GP Surgery.
But i wouldn't wish this all on anyone else - I'm just happy that i'm still alive so far & haven't slit my wrists during an irrational mood swing.
Because that's how it is.
Right now, this moment, I'm content, happy & want to stay this way for ever. But in 2 hours, 2 days, 2 weeks time? I don't know.
