I NEED HELP

I need to get some help
But they won’t let me in
I’m going off the rails again
But they won’t let me in
I need to get some therapy
But they won’t let me in
My medication has run out
But they won’t let me in
I can’t stand the pace of life
But they won’t let me in
They helped me once before
Why won’t they let me in?
The only reason they give
“There’s no room at the bin”
