I am probably going to regret posting this, but here goes, anyway.
I'm 21, and currently living at home with my mum and dad - I have a twin but they are at uni. I was, too, until earlier this year but dropped out as my mental health was awful: suicide attempts and an eating disorder which got so bad I spent time in hospital soon after returning home. I got a job, which I loved, but was sacked after 6 months (and they never really told me why).
Having been under community eating disorder services for several months with nothing really happening, my mum is now paying a private psychologist, who I think is helping a bit though it is early days. (For context, current dx are Anorexia Nervosa binge/purge subtype, EUPD, Psychotic depression, PTSD, and social phobia and generalised anxiety disorder, and I'm awaiting assessments for ADHD and ASD. I don't know how much of these are just services giving me labels so it looks like they're doing something or how much is actually true, though.)
I've been applying for jobs and am on benefits: so far I've had two interviews, and been offered both, but turned them down as I didn't feel either the work itself in the case of one, or the colleagues in the case of the other, were good fits.
The crux of the matter is this: I don't know what to do with my life; I feel so hopeless all the time. I have good A Levels and GCSEs (all A or A* or their equivalent) but no real qualifications. I don't know if I should look into studying again, but stay living at home; look for a job I can have a 'career' in; or what, really. I know I want to find a job (just not one that will make my mental health worse, of course), I know I want to pass my driving test because there's somewhere I want to volunteer at that needs a car to get to but my parents cannot take me as it does not fit around their work schedules.
A few people have suggested to me setting up my own business with a grant from The Prince's Trust but I don't know how it works, or how to MAKE doing such a thing work. Part of me, a large part of me, wants to curl up and die because I don't feel I will ever do anything or be anything that matters or makes a positive difference to the world. I don't want this part to win: I have many animals I care about very much, and who I will not abandon like that, even if continuing to live is agony. My parents both also have health issues which are exacerbated by stress, so I try and keep things from them (hence posting here - also because I want an impartial/outsider's opinion on things to offer some clarity).
Basically, if I was your daughter, what would you recommend I do at the moment?
TL;DR 21yo feeling very lost and hopeless and wanting impartial outside opinons on where to go from here, please.
