I don't have DID, but I have been hospitalized. It has groups all day, there are always people to talk to. I don't do well with hospitalizations (I tend to isolate myself in those situations so it doesn't benefit me).

I took ASL (levels 1-3) at my school! Both of my teachers were deaf, so I picked it up quickly and I still remember most of it. The grammar is tough! They cut the ASL program at my school though
