I agree with chris1234. Technology provides a career. What you suffer from, what many gifted adults suffer from, is narcissism and entitlement. Because you are smart, you expect the world to provide a path. It doesn't. It provides a path for those who sweat. It is great if you are smart but that is 10% of the equation. I think you may have heard that.
Yes, your home life was not great. I studied engineering in college with a woman whose mother had a serious bipolar disorder and she graduated, got a job, got a car.
You can let the circumstances make excuses or put that mind to work. Start jogging every morning to start your day and get energized. I live in NYC and there are stories of some kid in Harlem that gets up at 5 am to his homework so he can do his afterschool job and buy dinner. And he gets into Harvard. He is really smart but he also works for what he wants.
I am brutal because you are an adult now. If you don't stop making excuses now and take action, even if you take one step forward, find out what it takes to get a teaching certificate, you will be 33 and posting the same thing on this forum. My college roommate got her BFA and later her MFA. In between she got her teaching certificate and she teaches high school art. And has a studio there to do her own print making. She contacts art galleries for her students to show and at the same time makes connections to show her own art.
