Depressed and in denial

I am so depressed, but I don't let myself admit it. I try to force a smile, I try to laugh, to be happy, I am so tired of it. I feel so weak inside. I can't sleep. All I want to do is cry. Maybe jump off a roof or something. I wish i had the guts to do that because I would. What do I have to live for? I know what everyone would answer to that question; my daughter. She's better off without me anyways, who am i kidding trying to be a mother at 16. I wanna die. I wanna cry, I am so tired of life, and giving energy to nothing. I write this now and as soon as I get off the computer I will be in denial again, same process happens everyday, like a routine you could say. My life sucks. I wrote this probably for nothing..who wants to read about my shittyass life?? cause i know i wouldnt want to...
