I hate my life

I hate my life and sometimes wish I had the guts to kill myself. If it wasn't for knowing how upset my dad would be if I did then I know I definitely would. My job is shit, my relationship is shit and I don't feel I have any friends who I can open up to and admit all this too! I don't want to go on pills and don't want the stigma of being depressed with work etc. Life is too much at times and I don't know how to cope. I don't have anything in my life or close friendship groups but don't have the energy/willpower to do anything about that either! I feel like a lost cause and so pathetic! Anyone feel remotely similar?!?!
