You can’t do this alone. I’m surprised and alarmed that no one has helped you find a therapist or support group. People with autism often are easily over-stimulated and over-whelmed. Sometimes this leads to over-reactions. Knowing how to regulate your emotions, soothe yourself and handle conflict is essential if you are to be successful living and working on your own.
In your state, young people with special needs are eligible for support from the public schools until age 22. If you have not graduated, you may still be able to get some help there. If you did graduate, you need to find community support. When I did an internet search, I found this agency in your geographical area: http://www.tillinc.org/autism_support.html. That may be a place to start.
You are obviously intelligent and thoughtful. You owe it to yourself to put that intelligence to work. Find the help you need so that you can get along with others and function fully and happily in the world.
I wish you well.
