Paranoid or what?

So I'm just like.... I'm always terrified that all my friends are out to get me, or they're lying to me and they hate me and they're going to trick me. That's always in my head. Ive been lied to and talked about behind my back so much that it's just second nature anymore. But I can't handle it anymore. My best friend in the entire world has always assured me that he'd never say a bad word about me and that I'm the only person that has never hurt him and ETC. I started to ease into believing him and then I found out that he lies about me behind my back. He lies and says that I pressure him into things when it's always stuff he was the one to suggest doing. Now Ive noticed that he lies about everyone. I don't know what's real anymore. He lies about everything and I'm so terrified of being around him. How can someone lie so much? He just does it compulsively. He's actually roommates with me so it's hard to get away from him. I want to move away and never see him again. I don't believe anything from anyone anymore, i don't think anyone has ever been honest with me. Does anyone else feel that way? Nobody is ever telling the truth...
