SO this weekend I splurged and haven't followed my diet at all, could you help me get on track?

Its been an awful week, and I ate so bad this weekend to make it worse, and totally ditched my diet. My gf left me, I'm not following my diet, my friend ped away today (RIP Emily), had to go to court for a ticket even though I didn't do anything, failed 2 midterms, and lots more....please help me feel better. Give me so advice or inspriration, I need to be motivated, anything at all will do...please and thank you
