When Change Is The Only Constant.

I'm in a dilemma.. On normal days, I would love PE. It does help me destress sometimes. But for now, I just hate it. Not because of the exercises I get but because of what happens after the lesson. It's causing my skin condition to worsen.. Never has it been so serious. It keeps getting dried up and peels off frequently.. can you imagine the pain, especially when it comes to bathing (which is my favourite pastime and now my worse nightmare?) This would be my last time taking the fitness exam.. Should I just try to carry on with it? Even though I'm so stressed about it? :'( I feel like crying. This thing just keeps coming and the irritaion is immense just after lesson. Why go through so much torture..? Should I? Sigh..
