Just to put the dot back at the horizon, you can have a "normal" job. If you can find something you like and can (hyper) focus on it's details you can excel at it.
I've been going into electronics, and I make the same as my partner does. The hardest part of my job for me is the social aspect, but the machines at least don't need to be talked to. Being a man of rules and details comes in verry handy for programming and such too.
Another thing to note is that the generally noted "smartest" people in history most likely had a form of autism. It can of course not be proven, but they where hyper focused in the area they are known for. But dint know or where bad at other 'simpler' areas.
To come back to your question of making money at home, I would personally go into 3D printing or so. It's rewarding, lots to learn, and there is still room to make a buck
Make sure to check about SSI rules before doing anything btw
