I know this is not what the thread is about, but shift work is horrible for bipolar people because regular sleep is a core issue in bipolar management. Is it possible for you to get a regular daytime job instead? Since you are saying that you have everything, I am puzzled that you accepted a shift work schedule. Unless I misunderstood "have everything", of course.

Or was shift work something that you stopped doing? I am unclear from the post what you are doing with work now.
