I've been diagnosed yes, but i don't quite know who to seek for help(If it is available at any point). Any suggestion?
Well, it depends a lot on where you live. In the UK the starting point is often your GP, who can refer you for CBT or whatever. But also google to see what's available in your local area in the way of support groups, social groups, autism groups, etc. Does your school have a counsellor or would your parents pay for you to see a counsellor? Do you have a doctor?
Basically life is hard enough for 'normal' people, let alone those with autism. I was a depressive mess when I left school. I wish I had better some tips for helping you, but in truth I don't have any magic advice. I think one thing I would recommend is leave off worrying about
females until you've got your school and social life sorted out - if you really are annoying (and it's not just people trying to bully or shame you), then work on being less annoying in company.
Anyway, so yeah. From your star system it seems like school and Asperger's are the two things bothering you the most at the moment, so I would try to work on those first of all, particularly school - don't tackle everything that's wrong in your life all at once!
