I dont understand people.

So yesterday I tried to make amends with my friend who I have no been getting along with lately. I finally called her out on everything and told her about how I feel. Well she was at work so I did it through a myspace message figuring I could probally get everything out better in writing. Well this morning when I wake up I look to see if she messaged me back or anything but what do I find. That she forwarded it to one of her other friends who is the main problem out of all of this. I was so hurt by this that I literally just stared at the computer screen, and when I finally went back into my room I took the picture of me and her that was on my dresser and I threw it across my room. I dont think I have ever been this mad in my entire life. I also dont think I have ever been this hurt by a friend either.
Also today, I dont think I've ever met more immature rude people in my entire life. My fifth hour world lit class is rediculous. I was one of only two who actually did the reading the Ms. E assigned and everyone else just made excuses about how reading 10 pages was impossible and a rediculous assignment. I dont even think you guys can understand my rage. These past two weeks have been the worse in my entire life, like I though nothing else could happen but from more just happening I dont even know what to do.
I need this weekend to clear my head. I dont think I have slept a full night in a good 13 days. I'm never really hungry, and when I am I can take like 3 bites and Im full. I use to be like that when Im little as well as the migranes. I use to get them ALL the time when I was little and they are coming back really bad and ALL the time again. I have no idea what to do.
