rewin,

You are very smart and I think you can complete that work and those exams. I have suffered mental illness since your age and I found much solace in making good grades while in classes.

I say go for it. Yes, it is work, but work I believe you can do. I find deadlines as positive stress that spurs me on. Please remember that the work does not have to be perfect in order to pass. Don't burden yourself with having to have the best mark, as you typically seem to do. (So did I, just to realize that getting the passing mark was good enough and high marks mattered little in the end.)

I'm obviously no therapist, that is just my opinion and my experience. It feels really great to have it over with!

Best of luck to you.
