Last Thoughts

HELP PLEASE! Advice wanted! Its sad but its not descrbing me, but I wrote it.

I’m stuck here,
In a jail of misery and shame,
I look around wondering why I’m here,
What have I done to deserve this?
My arms chained to iron bars of cold and tears.
My mind engulfed by last thoughts,
I'm restricted in the valley of damp reasoning
Pierced by the thorns of regret,
I’m being suffocated in agony,
My happiness sucked dry,
I’m broken and never going to heal.
My life no point finishing it out,
It will be over soon,
Very soon.
