I'll be thinking about you and good luck when you start school. For the record, I'm glad I don't have to teach high school math. It was always my weakest subject, ironically. I did take a per-calculus class 11 years ago and squeaked by with an A. I amazed myself, but I studied 4 hours every day/night. You hang in there and keep me posted occasionally, or what ever is comfortable for you. Your friend.
