Chris, I wish I could give you an answer. I have what I think is an episode of GAD but it's just lasted
about 1.5 months. And I'm crossing my fingers it's seasonal to the winter and will go in the spring. Did you try to google your question?
I am also bipolar ii and I can tell you that meds and buddhist chanting has allowed me to lead a very normal life
without moodswings for 20 years. It's more a matter I think of finding a way to managing a condition, more than fixing it.
And I'm an optimist and believe that recovery is always possible, regardless of duration. My two cents.
