Only I'm to blame

Sitting here on my own
blocking out everyone
trusting nothing but myself
my long road has yet begun.

Ive been here less
than sixteen years
Ive seen to much
and done the same
mistreated myself
so only I'm to blame.

I don't see the point
of living till I'm elderly
Ive already had enough of my life
i doubt I'll make it through twenty.
