Nothing person

I don't know what I am doing here
I have no purpose, no goals, no dreams
I don't enjoy life
I know there's no future for me
And a person without future is nothing
It's what I am
I am a nothing person
Who has nowhere to go
I keep hearing this suicidal mantra in my head 24x7
"You're worthless and useless...so, just fucking do it!
No one will miss you when you're gone"
