Unlovable

My boyfriend of about a month and a half just broke up with me. I know that is not a super long time but we got super closer super fast. Im mainly writing this to process my own emotions since it happened about 3-4 hours ago. He said it was because he didn't want to get more attached before he leaves for college (he's a senior and i'm a junior) but he also said that he can't handle taking care of me anymore because he doesn't have the energy to live his life and fix mine. I've been struggling with depression and anxiety for about a year now and had my first appointment with my psychiatrist today and got medicine to help. He told me he would help me and that I could lean on him but now i just feel like a burden because he didn't want to to talk to me because I always talked about sad things according to him. I just feel like I'll never get better and that nobody will ever love me especially since he promised me that he would never give up on me because of my mental illnesses because he loved me too much. High school sucks
