How about the punk rock musical that kicks "Chicago"'s flashy, overproduced ass -- "Hedwig and the Angry Inch"? It's certainly a movie about finding yourself and moving on (in Farrah Fawcett flip wigs, no less).

Seriously, though. I've been there and the best advice I can offer is to give yourself time. Feel shitty and sad if you feel shitty and sad. Avoid the pressure of being happy, shiny Bonnie all the time. You'll feel better and things will get back to normal in their own time. :)
