My diagnosis is "cyclothymia with BP2 tendencies", which means I tend towards depression and mixed states. You will not know if you are hypomanic until it is too late, sad to say. Well, if you are anything like me and most of my members. You get up high and then can't get down when you want to and then crash and then comes the depression.
As the years have gone by I have increasingly come to believe that Cylothymia is Bipolar (so many doctors present it as separate) and that true Cyclothymics can pretty much manage without med as long as they do CBT. Technically the difference is that someone with BP2 has had a Major Depressive Episode.
I am on Lithium, Depakene, and Wellbutrin. I am supposed to be Cyclothymic but my meds are the same meds as they take with full BP2. I think it is best to think of Bipolar as a spectrum of intensity and that it is enough to accept that you are on the spectrum and take responsibility for your health and your relationships. Keep a daily mood journal that includes what meds you took and how you feel, and work with your doctor. Be your own health advocate. This is very important.
