I am certain your passion will eventually return to varying degrees. I know what you're feeling, though. I think some medications can be contributing factors, but in my case, depressed mood was the main one. Either way, do work with both your psychiatrist and therapist to get passed this. Sometimes it passes slowly, and sometimes quickly.

I am feeling very stable these days. I do feel I have a passion for certain things, but I recognize that manic elated passion is not something I should aim for as a norm. That doesn't mean we can't have special moments in our lives that rival that, yet still qualify as stable.
