The particular difficulty of feelng this sudden, overwhelming thingy (I call it 'freefalling through terror') started around the age of 12. It's possible I felt it before when younger but I'm thinking probably very young? Like 6 or less.
Wider stuff... I was a bit weird as a child, apparently, school had concerns (and parents felt judged/blamed so that wasn't helpful) but then sort of just punished/ignored me if I did anything 'wrong' like cry too much. By chance I lost a lot of close friends from nursery to 7yrs old (moving away), one of these - 'friend'- from nursery to reception was a horrible bully (I later met someone from the school she went to, this person had a moan about her and I was like Ooh I know that person!), so a sort of prototype abusive realtionship (having to do what she said etc.) I felt different- inferior - for most of my life until I suddenly twigged at 18 I was just like everyone else. Not sure now. I have wondered about aspergers but I dont know whats left without the trauma stuff.
I self-diagnosed complex PTSD a few years ago (I'm 30 now). At 19 unfortunately when I really tried to get help I believed that nurses were kindly beings and that psych nes would be just the same; I was clueles about the harsh realitites of the system. (Had been vaguely to GP at 17 and given AD's, which did nothing, and diagnosed depressed, but no CAMHS). So at first I thought the GP was just a one off evil GP, same with CPN... took a while to realise, I didn't have internet at the time but once I did I started googling... it was like uncovering a mass grave or something, so shocking what they did/do to people who by and large are massively traumatised... nice to know it wasn't me, but so terrifyingly powerless to stop the institutional abuse.
Sorry, rambling a bit, basically I absorbed their messages I was a worthless piece of scum who should just be fine (they used to ask why I called, telling me I was overreacting even when living with a violent man (not partner) - council wouldn't house me if I left saying I'd be 'voluntarily homeless', which is a lie but MH team wouldn't back me up). They used to get cross if I was upset or asked them when I could see a therapist/counsellor. They wrote a care plan that projected me magically getting better with no input/treatment
and got cross when I couldn't stick to that. They said the only problem was that I was contacting them, and called it as 'behavioural problems' - they literally thought me asking for help was the problem, they couldnt wrap their minds around the idea that I felt shite and needed help with something quite specific (if I could have held down a job I'd have been able to escape other traumatic things.)
Oops I've rambled again... anyway suffice it to say there was lots of things over a few years that were terrifying and painful - abusive relationship(s?), homelessness, sex when I didn't want to (but couldn't say no, so not rape). I interspersed these with some fun (in a desperate, driven, "I have to make some good memeories" way) but you get the idea.
Thought everything OK and much happier then lost budding career (due to v questionable criminalisation at 19, MH team trying to get rid of me), ended up breaking down just as I thought I was happy. Around this time I started getting specific memeories of things, ended up self-diagnosing complex PTSD at this point. Obvs what with the stuff in early 20's - I might actually be largely 'over' the earlier stuff.
A lot of it's terrifying because stuff happened that was wrong. I was arrested many times on a whim, really, like they had a standard procedure to just lock me up asap to make sure I wasn't dead, but not to actually get any help. But on two occasions there was violence in the house (one time I was thrown into the street and shut out of my own home not properly dressed) and they wouldn't come when I called. People don't believe this stuff. I feel so alone with it.
I see a therapist privately but I think feeling so alone irl isn't helping, because it's so much harder to explore stuff. Because if you open a can of worms there is no support.
BTW the crappy GP had no right to pre-diagnose but I think he did - certainly I was treated like scum from the start. It's sort of as if they took against me straightaway which led to the BPD diagnosis, not the other way round. The GP was very disinterested, said I was probably "just one of those people" (after glancing through notes and seeing concerns from young childhood) and said I HAD to take AD's or he wouldn't refer me on. Had to really push even for that. People also dont believe how bad services were/are, it's incredibly difficult to be kind to myself and put things into context when there's no reassurance from others, because if you told them they'd think you were making it up.
Im sorry for writing so much, had the most awful conversation with crisis team just now. It's like they're trying to make it worse. She kept saying I was shouting at her, when I really wasn't (if voiced raised unintentionally in upset why take it personally?), and telling me I was winding myself up, when actually I was calm when I called but it was her attitude that got me. How the fuck do they expect a very upset person to remain calm when faced with their bullshit? She kept interrputing me, woudnt take in what I was saying. Oh, and apparently flashbacks are my fault for thinking about it 
Im sorry, bit of a mess right now.
