Take up a new hobby, one you've put off doing for years.

Seek out positive people who are not mean, selfish, angry, in your face. Being around "good" people helps me feel all is not so hopeless after all.

Read inspiring books. I have been reading a book recently about women with DID who lead productive lives. It is inspiring reading about their contributions and the ways they cope and even turn their DID into a strength. I'm drawing a blank on the name of the book, but if you are interested, let me know, and I'll look it up.
