I haven't read the entire thread as my head hurts but it is entirely possible to have stability with bipolar. I have been stable years at a time with the correct meds and therapy. Of course the depression and mixed is inevitable after a while but we now know what meds help me quickly and then the reminders of my previous group work and therapy help too. I have way more coping skills than I had when I was first diagnosed which also helps keep me stable. I need to work hard every day and challenge myself with the anxiety. And keep in routine. I'm currently unstable due to extreme stress and that I didn't use the correct coping skills at the onset.
