Please don't lose this "financial aid" opportunity, try again and if your health condition still makes you feel uncomfortable pursuing the course, reduce your load or give up again.

"before you see the rainbow, you have to deal with the rain first" . . . you won't succeed should you not try.

However, if your health condition does not warrant and you are satisfied of how you are doing now, put off career issue for now. I really wish that I can be of help.
