I have no motivation to school work or find new people to talk to. I barely get sleep and always have no energy. Im shy and dont like being social. I mostly lose motivation because of how lonely i am. There is a girl i like but i know i cant ask her out and know im unlikable. All my good friends dont care about me anymore. I want to lose weight but dont have the motivation nor tools to do that. What can I do or how to motivate myself  so i dont have to live this life anymore? I dont know whats wrong with me
