Why?

I try to see why, but I’m blind.
I cant remember how, I cant remember why,
lying here tonight and I can't make it go away, now I cant stand the pain..
How could this happen to me?
I made my mistakes, but it was not on pupas
I want to start this over again, but is matters, it cant work.
I’m sick off this life, just want to go away.
explain it to me ...
