You said you like building and making things. Why don't you pick a building trade?
If you are young then you should consider taking some courses at a technical school such as dry walling, brick laying, or any number of skilled trades.
If you are older there are plenty of places, if you look hard enough, who will hire unskilled labour and you can learn and grow.
Starting your own business is hard without money and experience but you can almost always become a house painter.
You can never completely escape dealing with the humans but you can cut down the number with whom you have to deal.
You really just have to take on some people skills and deal with it. No one owes you anything and life is hard. You just have to deal with it. Keep looking at what other people do until you see something with which you can cope.
I'm an artist and I understand. I've had to do many jobs I didn't care for but I did find some satisfaction in renovations and taught myself how to drywall and I already knew about electricity so I'm a really good unlicensed electrician. You just have to keep looking and you will find something.
