That Familiar Feeling

...of drowning again. The same feeling of a lowering cloud of doom presented itself when I woke up. Dragged myself into the shower and feeling angry at the world, I delivered a few punches to the wall. I felt somewhat better or less violent anyway and finished my shower.
Then I sat on the bed and cried. I started crying really loud so I stuffed the towel over my mouth. Later on I did work the knots out of my hair and put on some clean, if worn out, clothes.
So how do I work the knots out of my life? How do I get over this feeling of being trapped, of being held back by my illness from accomplishing even the most basic things that seem to come so naturally to others?
