of all the thing's I've lost - I miss my mind the most

I've found myself at a road block. I want to write, express, create and release - I want to speak what's on my mind. Instead I find myself filtering my thoughts - ruling out my opinions. I find myself negotiating with my own mind, a self-conscious tweak to everything I am trying to express. I don't know when I lost my confidence in my ability to say what I need to say - but nothing ever seems to come out right. I can sit here, typing and erasing over and over again - it doesn't matter what I'm writing about or what I'm trying to say, it all just seems to come out like jibberish. Maybe I just need to sit with my thoughts for awhile, maybe I need to take a break for awhile. I hope it's not long..
