I (20F) feel like my life is in shambles. My girlfriend (19F), whom I love a lot, broke up with me because she never wanted to get married but thought I did (I don't, I just am a shitty communicator). My parents are so overbearing that I feel like I can't develop my own personality or goals without losing their love and ruining my life. I constantly have episodes where I am convinced no one loves me and I should die, and even when I'm not feeling that way I have no interest or motivation in really anything. I am miserable in my life, and I need to change something. 

What should I do? I go to therapy once a week and take antidepressants but I feel like more needs to be done. I hate the way I've treated my ex gf and friends so poorly because of my insecurities, yet theyve given me so much grace (my ex has said she would be willing to be friends or maybe even reconcile if I get help) and I feel like I owe it to them to not give up on myself since they haven't given up on me. Plus, I hate feeling like this.
