If you're gut is telling you to stay in by all means do what feels best. Supportive friends would understand and not make you feel bad, and if you're that close (which it sounds like you are) just let them know how they make you feel. And, since they are good friends they should knock it off. Just keep up your great work and know this IP P1 isn't forever. Soon you'll be back in the swing of things with them and LOOKING INCREDIBLY HOT!
