Hi
I think that going back to school is a good option. Otherwise you may be stuck in retail. I dont know that you need SAT/ACT or great grades to attend a community college. Plus you can get financial aid (Pell grant) to pay for classes. It couldnt hurt to make an appointment with a guidance counselor at your local community college to discuss your options. You dont even need to know what you want to do with your life to get started because the classes you need to take are just the basics. Its the same for everybody. Doing something, anything to address your future needs will make you feel better.
