fluffy - re: the Psychiatrist's attitude - mine is similar.
I have BPD & Depression too but unlike you I do have irrational thoughts & short psychotic episodes when i feel very suicidal, & he knows this.
I don't see reality in the same way when i get those episodes; & he acknowledges that.
But i think he doesn't want to section me because half the month i'm not depressed or irrational at all - PMT & anxiety are triggers for my problems.
That's fine by me; i don't want to BE sectioned. So i minimise the risks by not keeping sharp knives, & have put notes to myself in the house (& cutlery drawer) for when i do get psychotic or irrational episodes.
Personally it sounds to me like you do need to stay in hospital, or have someone stay in your home.
Psychology would really help you but you need to be more well for it to work.
My Psychologist has helped me to recognise the warning signs & triggers for when i get unwell so that i can 'take control' of my condition.
Returning to work after 5 months helps because i'm focusing on other people's problems & it's grounding me in reality more.
I work 2 days a week now which is ideal because I can focus on patient care which is important to me (i'm a nurse) & be sociable with my colleagues.
I'm not there often enough to get dragged into the staff politics & bitching, which has made me very paranoid before.
Plus my managers know my problems & are looking out for me - they were the first people to realise i was ill in the past.
Re: your self harm - i have done that obsessively at times but nothing as bad as what you have done.
Ironically being a nurse means that i'm conscious of wanting to avoid A&E at all costs; plus i have that knowledge in my mind of consequences (eg. i've cared for people who OD & got liver failure but lived long enough to regret their suicide attempt - so tragic & a waste.)
Also i know the risks re: infection - i've seen amputations due to infection.
The only way i would suicide is by cutting my wrists so i avoid sharp knives - i tried it but the scissors were quite blunt then before i did it anyway my stupid cat jumping onto my stomach wanting a fuss which made me laugh - my cat saved my life which sounds quite funny actually!
I know you have OCD but seriously - when you get home you need a cat - when i'm depressed i get paranoid that mine will get hurt outside, so i have to keep her indoors then. & she then goes out of her way to be annoying which is hilarious. I feed my cat even when i don't feed myself, & brush her daily even if i can't be motivated to get showered & dressed (well she gets sick with furballs if i don't brush her - yep i got a 'cute' Persian & they are hard work & demanding - oops).
If A&E wanted plastics involved (eg skin grafting) then your wounds must be pretty bad.
You have to stop & you know this. Or you WILL get nerve damage & could lose the sensation in your hands.
Killing yourself is not so easy either. Once you cut an artery you DO have time to regret what you've done - i've helped to treat arterial bleeds.
Jumping off somewhere - well you could break your neck & end up paralysed, or break both legs & need bedpans for months.
Hanging has deeply unpleasant consequences (not spelling them out) - & again, if you slowly strangle there's plenty of time to regret it.
OD's don't always kill you. You could go blind or damage your organs.
Then consider other people. Nurses, doctors, paramedics & police may act jokey, hard, even uncaring but actually it's all an act.
When we see someone badly wounded (like with your self harm) it's very upsettting obviously.
I have friends in the 999 services who deal with suicides, a little bit of themselves dies with each one. They do get badly affected by what they see, & often drink heavily to hide it. Some won't admit it - even i did develop a hard shell when i was a student nurse & saw too many deaths - but when that shell breaks that's when healthcare & 999 staff can get ill too.
Think of how they will feel to see a person like themselves dead (& trust me it's very very final) & in a disgusting mess - dead bodies decompose very quickly & it is horrible. You learn to live with what you see, but your case could be the one that destroys the person who has to see you - that is one bad legacy to leave, & that is why i don't want to kill myself ultimately.
You need to develop strategies to stop the self-harm.
You are obsessive, so am i. You can't stop being obsessive until you have therapy for that - so just get an obsession or two that take up your time & energy but cause no harm or distress to you or to anyone else. Eg. some kind of hobby, study or exercise that will get you connecting with others.
You can connect well with others - your post shows that you have empathy & are intelligent. So do that.
Make sure you are referred for therapy - ask for DBT.
Listen to the Psychologist that you will get (if you don't have one now) & also phone the CMHT Crisis team every time you need to.
If you are anything like me then you will think others are more important than you. For example if my Mum was suicidal or self-harming then i would make her live with me! But i keep forgetting how she must feel when i do it, when i'm suicidal i just want to end the pain, or i just feel that i must do it, or i feel like i will be doing everyone a favour.
Well that's NOT the case (currently i'm much more well so i can see that) - you WILL begin to see that as well when you start to recover.
Until You start to recover - write down this & stick it up in each room of your home:
I do not really want to kill myself.
My thoughts that i must kill myself are totally irrational & caused by underlying anxiety.
Death is disgusting.
Cutting & burning will give me dangerous infections & irreversible nerve damage.
Suicide will cause severe distress to others including professionals & i do not want to cause distress to others.
(Write down a list of activities that will then distract you - both in your home & outside - even just going to sleep for a bit may help)
(Also write down - 'call the Crisis Team - they want to help me even though i don't think i'm important because they would not have jobs if people like me didn't phone them' - 'I must phone them before i self-harm because they would prefer me to phone them & not self harm').
Finally get a shoebox - call it your 'happy box' (yes sounds daft i know).
Fill it with your favourite photos; any positive notes / cards etc from others; funny jokes or funny books; funny DVDs; CDs that are uplifting & you can dance around to. When you feel depressed then look through it.
And keep a reminder to eat healthy low sugar, snacks - because food can really help to lift your mood.
PM if you like. Take care & remember you will get well.
Ps. think of stopping self-harm like stopping smoking. It's very difficult but it has to stop & you CAN stop, because self-harm causes so many problems.
