ThinkTheUnthinkable

What would you do if you received a text like this from your best friend?
For the past few months, I've been through what feels like a life time of pain, anger and regret.
And I am so sorry for the way I've been treating you. Blaming my own misery on you and trying to make you feel how I do.
I lied to you; I have cut, many times as it seems the only way to escape the reality of it. But right now, it doesn't feel like enough...
"Suicide is never the answer" they've all told me but I cant think of anything better.  My hands are tied.  Of course I
  have another choice, but what would that mean? Facing this life I call hell? Living a nightmare unable to awake from it?
I know  thee world be a much better place with me out of the picture and that's why i have made this  decision.  Don't miss me, don't mourn my death, don't cry. Move on and live your life as if i never existed.
One day you will grow up, get married and have beautiful children and i will be forgotten... And that day you will realise this choice was the right one.
I love you. xxx
