Hi @BlitzedWolf,
What I like to do, is to try every doorknob (figuratively)... whenever you find one that's unlocked, go in.
Everything you do is an opportunity.
And, everything you don't do is a missed opportunity.
So choose them wisely, but choose as many as you can. Time's a-wastin'.

It doesn't even matter what it is. If your skills are not "in demand" for any steady jobs that are available, then... get in demand, by doing whatever is available. There are no wasted experiences.
Somebody needs help doing something. I don't know your community, but the Church, or the Animal Shelter, or the city putting on an event... I don't know... anything.
Each time, you'll pick up a new skill or two maybe, and you'll meet some new people. The thing they'll remember most about you is your attitude, and whether you were sincerely there to contribute the best you could, and your phone number... don't forget to give them your phone number.

You already know you've got more to offer, that's why you're looking for ways to offer it. You just have to get out there and resume the slow-but-steady work of accumulating skills and contacts.
Also, don't hold back. You have to be willing to look stupid and to fail; and to remember that we all do exactly that all the time, whether we're willing to admit it or not we all know it's true.
What I like to tell my teams, is that if you never fail... you're not trying hard enough.
You almost never get a new thing right the first time. You'll have to try again at least once... after learning some small lesson. So, what does that tell you?
It tells you that failure is, ironically, the path to success.
Be glad when you mess something up, it means you learned something and that you're on the right track to succeeding eventually; as long as you learn from it and keep trying... that's all that matters.
If you haven't given up then you haven't failed, you're just not done yet.
And, don't forget to take a moment and be proud each time you get it right, because you just "leveled-up". That's why I say that everything you do is an opportunity. Because the more you level-up, the more you bring to the table next time, and the more it will be worth it for someone to compensate you to get you on the team.

It sounds like you don't really have a direction that you're settled on. That can sometimes feel like you're "going nowhere", and like by the time it's all over you will have never gotten anywhere at all. I think it's natural to feel depressed in that situation, and then even less-motivated to do anything about it. But don't forget that it is a temporary situation and it will be fixed whenever you do something to fix it.
When you start zeroing-in on a specific career field, ask around. Find out what specific qualifications or certifications those people have; then you can set your long-term sights on filling in those check-boxes.
By then, you'll be the best damn choice on the list of applicants. Remember, when somebody's hiring for any position: they're not doing it because you need a job, they're doing it because they need you.
Find out who they need, and be that guy.

Just get up and try to be better everyday. Start exercising and make you a schedule and stick to it. You are among billions of us who suffer from something. It's not an excuse to do nothing with your life. I'm sorry no one has said this to you. You have to find out who you are. The only way to do that. Is to try to do some different things.
I to was very socially awkward as a child, no friends. Poor as dirt, and made fun of. Fortunately I had a momma who never let me feel sorry for myself.
You can either get busy living. Or get busy dieing.
It sounds like you want better. So go get it. No one is going to hand it to you. Everyday wake up and say 3 good things about yourself. Even if you don't believe it right now. Over time you will.
Your thoughts and actions control who you are. You should never let anyone else determine your self worth.

If you have a “highly psychological” way of thinking, write your thoughts down. And read. And read some more. And then keep writing. Expand your “hobby skills” into art. Everybody in this life has something to offer and everyone has the potential to transcend their suffering. You are no less important than any other person on this earth. Don’t give up.

Write a novel and develop a comic strip. Starta podcast about autism.

Would getting a job disqualify you for disability? If so I would not risk that at this point. I'm not a professional but you sound, understandably , depressed to me. It is incredibly difficult for people to make good decisions from this state of mind. When we feel good about ourselves and our self worth we make more positive meaningful decisions.
I have found that when I am feeling down it is helpful to me to get involved in helping other people overcome something they are experiencing. This will lift your spirits and put you in contact with a greater number of people. One of whom may be able to help you achieve your objective of independence.
I look for things to encourage me like this video

Nothing wrong with thinking as long as we think correctly. if you want to be great, look for ways to serve...

self employment is a great way to get started back in life...you work at your own pace you don't need to declare your income....i mean like cutting grass or yard work in the neighbour hood etc. small jobs do you have a drivers license?

first off, get a voluntary job. there are lots of charities looking for helpers. that is one way of learning new skills. it also puts you in contact with lots of people who may be looking for someone to do odd jobs. you can mow grass, shovel snow, sweep floors. i worked in a company where the man only mopped the floor twice a day. another man i knew worked in kfc, he loved his job, i am sure it was simple but he was happy.
