It is possible to get disability benefits with autism, though it will probably involve a detailed evaluation of the specific traits that you have that prevent you from working, eg. meltdowns, anxiety, problems with communication, manual dexterity etc. The process probably will include some consultations with doctors and psychiatrists/psychologists, and might depending on the situation some type of work testing to find out how much/how effective you would be in a work situation. If it shows a low ability to handle work then its likely you could get disability, though if you are showed to have a moderate ability to work perhaps you would get assistance with placement at a part time job with accomodations for your autism.
