I absolutely question my diagnosis from time to time. I fought hard in the beginning to accept that I was going to live with bipolar disorder. During some of the more level stretches, I would begin to doubt that I was sick at all. And during some med changes, if I was not doing well, I still would believe that I was well and didn't have a mental illness to deal with. There are times I feel that the meds did maybe cause symptoms and that the meds were the enemy. I learned the hard way that I had to buckle down and accept things the way they are. But I think it's part of the process to question our diagnoses. All the best. Stay strong!
