had enough

If God came and said to me right now "i can see you have had enough, would you like to die now" i would say yes, i wake up every morning and wish i hadnt bothered. I am so tired of fighting and failing, i am so exhausted anyway from everything i am doing, I am a constant failure.
I am sorry I havent been on here much over the past week, I just couldnt, i feel like such a failure and like I have nothing to say anymore. 
I just dont know what to do.....
