School Midterms...failed.. life sucks?

I need help. Life hurts. I try to look at things in perspective and say, "I have a good like. I should be happy." But I have major self esteem issues, trying to lose weight with this thyroid condition that I have and neve even had a cute guy look at me. Last year I had a bunch of guy friends, was happier and did very well in school. My grades were basically A's and one or two B's but this year I'm stressing. With all the flues going around I was absent for more then 11 days which means I have to p all my midterms in order to get my credits. I have advanced cles so it's been very stressful. I was already upset that my grades were so eh (CACBBCB) but now I fell sick. I think I got a D on my AP History. I think got a D in my AICE GENERAL PAPPER and in my science....and the one thing I thought I did really well on I got a D. I'm going to hate getting my report card this semester. On top of that I almost got a zero and a referal...and I never get into trouble. And my teacher gave me a panic attack and I almost fainted in front of her. Oh and my Birthday is comming up. I feel lost. I heard colleges only see your midterm and final grades on the transcript. What do I do.
