Gosh.. I know how you feel. I'll be doing that in the Fall. I was supposed to take summer classes but cancelled both since I knew my body was barely making it. 1 more year of school!! (+grad assistantship + internship in a Hosp + my 3 lil monsters). I really do hope you get some rest and give your body a chance to relax.. with school and work and everything, you're amazing but definitely cut yourself slack if you need it!!
