im fucked up to, i wont go into my problems but look at it this way.
in all honesty, if you REALLY do think you are horrible, and you see suicide as the easy way out, but you want to make amends and help your daughter, then seriously do everything in your power to STOP DRINKING, lead your life for the next month or so ONLY thinking about her, not your problems whatsoever
your daughter is gonna be in a whole world of shit worse than whatever shes in now if you were to just up and kill yourself. Of anything, you are lucky, you know that whatever happens, you have someone you know at least needs you in some way. No matter how horrible you think you are, your daughter needs you alive.
Ive never felt needed in my entire life, and i would give just about anything to feel that way.
considering i found this site today, its my first post and whatever im not suggesting you take my advice, just think about it, as it is my view on what seems to be your problem
