When I went back to school and was afraid of Algebra also, I found there are tapes at the local library on the subject (and many others) that really helped me to step through the problems. I brushed up a bit before starting school, then used the tape periodically during the semester to help understand what we were working on at the time. Don't worry, it's normal to doubt your self, but you'll do just fine. And congrats on going back to school. I went back in my 40s and found I really enjoyed it.
