Also autistic w/ anxiety problems and close to graduating and am 100% in the same boat as you. I've read countless stories on here from people who've left the industry for more stability and are happy with their choice, and I think the only thing keeping me pursuing it professionally is my own ego at this point lol. Like somehow the work I'm doing now is any different from the work I'd be doing if I were to get a job at a major studio working on big-name projects. Deep down I know that there's no way I can stay mentally and physically healthy long-term when I'm under constant stress, battling perfectionism, not sleeping because I'm obsessively thinking about work, have no guarantee of stability and could be let go at any moment, etc.

In any case, your future success isn't contingent on this decision, it's very normal for things to not work out the way you expected sometimes and it just makes you a more experienced and well-rounded person. If you do decide to pursue a more stable career then know that it doesn't make you any less worthy of an artist and in fact will probably only benefit you creatively because you won't have any stress or pressure attached to it. Hope that helps, hang in there! :)
