My parents are getting divorced ...?

i'm fourteen and my parents are in the middle of a pretty messy divorce. i'm in the middle of constant conflict, and there's already SO MUCH going on right now. i just started high school, my sister left for college, my friends are turning on me, boy troubles, midterms, HORRIBLE period pains, nightly sports practice... i need ways to relax and keep from crying, stressing, getting stuck in the middle... any advice? thanks.
