If I may, here is something you may wish to think about. Since you were unable to find work for 2 years and went back to school, and since you are unsure of what you wish to do right now, here, today, why not follow through with your schooling without any regrets?

Education is so important these days and to not continue it through grad school, I think you would be doing yourself a disservice. Think of how good you can feel about yourself when you get your degree. Think of the possibilities that can come available to you after graduation.

Can you continue to do some of your artwork while still in grad school? Even if you only get to work on it for short times, it's better than no times right?

May I ask if you believe in God or a higher power? If so, why not ask God or your higher power what they want you to do?

Just my 2 cents worth.
