Family shit and depression

I can't deal with my life anymore, I have a break down once a week, suicide thoughts are common occurances and it seem that even the smallest of hurdles break me down.
Tonight, mid fight with my mother she said she wished I hadn't breathed after I was born. I'm now up in my room listening to my mum and dad fight about her drinking problem and I just want to kill myself. Not have to deal with anything in my life anymore.
