It's a tough spot you're in. You're young so you want to experience life and participate and have a career. But you've also got to cope with bipolar. I agree that you should ask to work only the hours allowed by your benefits and quit if they can't accomodate you. Steady income is really important to help achieve stability. It's been the greatest single factor in my recovery. Best of luck, you're an excellent writer despite your distress, very apt and bright from the sounds of it. There will be other opportunities!
