Once, voluntarily.. I kinda liked it. Getting there was terrifying. The first day was scary because there were people crazier than me there. Now I think of it as a safe place, a place I don't really want to be because of what it represents (me not doing well) but an ok place. I actually have an emergency bag and list of desired items should I have to go again.. last time I went with nothing but the clothes on my back.
