The best way to **** yourself?
The answer is simple:
Don't.
Being alive is not the same as living.
I might as well be dead by the way I feel.
Isolate yourself.
Don't speak when you want to the most.
Fake a smile.
most importantly stay alive, but don't live.
That's the best way  to do it.
To stay alive but feel so numb and sad that it slowly kills you all together.
