I'm making a real effort these days to plan stuff to do...even if it's just going to the farmer's market, library or whatever. It goes into the diary and onto the to-do lists! A yoga class would be great for that! And schedule new recipes to try to expand your foods.
I'd talk to your doc about the a-d's. Everyone reacts differently to them and it could be that another one would suit you better. I've done great on Celexa personally.
