I have no experience with staying at a mental hospital, and I'm not fearful of germs, exactly; I'm not afraid I'll get sick if I touch something...it's just this horrible feeling of being contaminated or dirty (those aren't the right words, but it's the best I can do to express what I feel). Being in such a hospital (or any hospital) would make me feel dirty. I could take their pills and eat there, and while I'm there I would be dirty but couldn't get clean. However, once I leave, I'd want to wash, shower, brush my teeth (to the point of drawing blood), and get it all "off" and "out of me" as much as possible.
