I need your suggestions ASAP. Please

Im back at school again. I hate it. Im around people who say they are my friends but it doesnt feel like it. I feel like Im gum stuck on their shoe that they have to carry around. Im panicking inside every time I have to even speak to them. I live with them and Im always in a state of unrest. Ive been told that Im a conversation killer by one of them and another has told me that they didnt like me not because of anything I did...but they just didnt like me. Later she said it was a joke. I never told either of them that this hurt me even though it was years ago. I spent my summer either in my room or at my internship. I felt safe. But now Im in school and one of them is here. The rest are yet to come from home. I have anxiety when its just me and one other person. I feel the need to entertain them. Make them happy. Feel useful to them. Im always scared that they hate me. They are tolerating me and that Im boring. I know I am but Im in my room that I share with her shaking and scared. I smile at them all the time. I try my best not to show...not to look more weak and useless...but Im scared. How do I make her happy...how do I make them all want me. Please help tell me something....anything...
