My Poison Prison

I use to be able to write 
Now with the words I fight 
In moments not so old
Every feeling was so bold
Every word that did cross my hear
Could stir a passion or a fear
Morbidly self obsessed
The doc says I'm depressed
Now I find myself in a poison prison
Locked away they claim I lost all mental reason
Forced to medicate
With pills me they suffocate
