You are definitely in my thoughts & prayers!
Sometimes I have the whole self-doubt thing (almost ALWAYS around final exams...) and I've found what really helps is a couple of hours of just *YOU* time.... some of my fav things do:
* deep clean pores with a mud mask (about $3.00 at your neighborhood grocery store!)
* soak in a bubble bath with lots of candles, and a warm bead eye-mask (can be found at the stores for about $3!)
* sit down and read a good book for fun. (we all know we HAVE to read for class, but read something you really want to... even if just for a little while!)
* call up that friend you haven't talked to in awhile and catch up (this will help you relax, as long as you don't talk about all the stressful stuff you have to do)
Above all things (and I'm sure you probably know this, but sometimes we all need some reminding) *do not procrastinate*!!! It is your enemy. Otherwise you'll be feeling 1000x worse in a few more weeks.
I hope everything works out for you and you achieve your goals this semester!!!
L&L,
