They all hate me because of my depression

My girlfriends whole family hates me because of my depression she got mad at me because I got frustrated and now she won't even talk to me. I'm crying because she is only one that sees how much progress I have made. I want to kill myself. My suicidal thoughts are starting to come back. Her dad thinks that I'm a loser she told me today that I am lazy. Now I feel like so much less of a man because I'm crying over this I shouldn't crying. I don't know what to do with my life anymore.
