I want to die

My whole life I’ve been depressed, with moments of happiness but nothing ever lasts, im so tired..every part of my mind tells me to just do it and I can’t get myself to. I’m scared that one day I’ll just give up. I have a daughter and when I look at her I just know I can’t do that to her but...sometimes I think she’ll just be better without me. I’m tired of arguing and fighting and feeling like shit all the time. Even when I try to get better something always brings me down. I just want to bang my head into a wall and not stop until I die. I think I’m just waiting for the right time to do it and it never comes. What’s the point of going on if everyone around me doesn’t see what their actions do to me. They don’t see me screaming for someone to help me . I don’t know how much more clear I have to be. I hate my life , I hate crying, I hate having to fight for every single thing and somehow it all being my fault
