Feeling down~

Recently, I have been very emotional. I get angry easily. I feel sad most of the time. I wanna cry. I feel so small, so useless, so lonely. I know people around me are saying me fat behind me. Some of them even have a nickname for me. People usually pay attention on the one beside me instead of me. They can totally ignore me and talk to the one beside me only. Well, I understand. I am short, fat, ugly and seems not as friendly as the one beside me. They don't even bother to be friends with me, of course they won't even bother to talk to me. I know. I feel like I am being ignored.
Almost most of the test 1 results are out. I don't score high marks for most of it. I did study very hard but I still get those rubbish result. Can someone tell me why am I so stupid? Why do I still get low marks after studying so hard? WHYYYYY????? I am very disappointed with my myself. I fail to impress anyone on any matters.
While I am so down, I try to find someone to talk to. There is this friend, when I told her about my situation, instead of comforting me, she asked me a question. The question sounds "No people talk to you is it?". I was so disappointed with her. She call herself my bestfriend and this is what I get in return when I need her.
I think it is time for me to have a makeover. I will those who look down at me now to get a heart attack. Wait and see.
