Another fucked up day

I pushed another person away today. I push every fucking person away. I feel like people would be better without me in their lives. I cause nothing but pain and all I want to do is hurt myself. I can’t control my emotions, especially my anger and I just snap all the time. It scares my girlfriend and I wish I could make her life better. The only way I feel I can do that is by ending my life. I don’t want to die but it is what’s best for everyone else. I feel like over-dosing today. I want to but I’m scared. I don’t know what to do. I just want to go away.
