How do I stand on my own feet at age 29?

I am turning 29 next month, and I am growing increasingly concerned because I am still financially, mentally, and emotionally dependant on my parents. I still live at home and haven't lived on my own more than a few months. I also haven't held a job for at least a year. The longest I have held a job is 8 months I think. I have had 20 something different jobs ever since I was 16.

Right now, I am on social security disability (SSDI), so I am restricted on the additional income I can receive without it affecting my benefits. I can only make an additional $1400 a month on top of my benefits.

I am realizing the only people keeping me from being homeless is my parents. That is a scary thought.

I am on the Autistic Spectrum by the way and have mental illness.
