I think of a "cure" in the same way I think of winning the lottery. What would it be like to suddenly have $20 million. What would it be like to be "normal".
My depression comes and goes. I have triggers, and I am starting to learn exactly what they are, and how to combat them. Reading here, and getting insight from fellow sufferers has been a god send. Blogging has also helped. It's amazing how putting everything down gets it out of your head.
I don't know about a cure, but I believe that remission is possible. I'm hoping my remissions will start lasting longer than my episodes.
