Gonna jump in here to say that you have all the same concerns and worries that everyone else has as they are navigating this thing called life.
It's hard OP.
And if you have some degree of learning disability, even mild, and autism, it just adds to the difficulties that everyone already has.
But it doesn't make all the things you want impossible. Just that you might need more support, you might have to stop and think things through a number of times before making choices, etc, just to make sure they are wise choices and been thought through. I'm not saying you don't think things through though, it's just if you have some learning disability, there might be times when you haven't seen the whole picture on things.
Have faith in yourself, listen to advice from all the people around you and if you feel you need to speak to another professional or independent person for support or assessments, ask for it. Always keep your eyes open for people who have your best interests at heart as you go through life.
You clearly do reflect on things as you are doing that here. And you clearly want your independence and autonomy. So I would say tell those that you trust that this is what you need and you need them to support you to make your own choices in life.
You asked earlier how to deal with people who don't want to talk to you because they sense you are autistic? (something like that?) Again we all deal with that stuff, maybe some of us are not autistic but we have other things that people shy away from, and we have to find ways to deal with it. I know someone who cannot hear properly and people back off, thinking she's odd, but she's learned how to deal with it by telling them straight away that she can't hear. Now most people are better with her because now they understand. So it's the same kind of thing in a way, you find 'coping mechanisms' like that for dealing with people that back off. And you also put your energy into people that make the extra effort for you. I wish you well OP.
