Hey. I'm so sorry for your situation. This world really is so unfair to so many people,especially those that are kind hearted and don't deserve that fate.
I used to have autism to some extent(still do technically but its much better as I've aged). What I mean is that I have major medical issues. I used to have even worse mental problems and I was very socially awkward. I couldn't tell if people were joking or serious,I couldn't communicate right at all whatsoever,and always made a fool of myself. I couldn't really understand if someone didn't like me. My brain fog didn't help with that either.
At 21 years old now,I admit I'm not bad off that way anymore,but I still have some trouble socially,mostly because I don't like being around people for long periods of time,if at all. I think I've just adjusted a bit more to effectively communicating,especially working at my job. I was really bad though for the first few years at my job. Only recently have I gotten better.
So I can understand what you mean,although I didn't have it as bad compared to others out there. I'm not trying to compare myself to you. I'm just trying to let you know I understand more than some people.
I do know that there are those with autism that learn to cope and meet others out there like themselves.
If you want to talk about your situation,I'll be here for you. Hopefully your parents, or maybe friends(?) are too. I know I can't do anything to help you medically,but again, I'm here if you need someone.
I wish you the best.
