Sick of school, etc.

I've had a really stressful week of studying for comprehensives, not feeling well, being tired, etc. We have 2 weeks til the big practical, and then 2 days after that, we have our written examination. I can barely take it anymore and I'm thissssss close to giving up and not studying and just hoping that I pass the tests when I take them, and hope I remember stuff I've learned the past 2.5 years. Although I'm very tempted to quit, I know that I have to do all I can do and then Heavenly Father will take care of the rest. So I'm hanging in there, but by a very thin thread. So please pray that I survive the next few weeks!!!!!
