I was diagnosed with major depressive disorder and GAD in 1987. I took a tricyclic (imipramine) with clonazepam and a very small dose of nozinan (5 mg) for 7 years. I was hypomanic but very functional. Too functional. I had 4 businesses that went nowhere. I also had a full time job and was offered a big promotion. I had to turn it down, because we moved home to look after aging and ill parents. After we moved home, I was put on SSRI'S. 26 years after my diagnoses of MDD and GAD, in 2013, at the age of 59, I was diagnosed with bipolar 2. That diagnosis explained my entire life. I now take a mood stabilizer, an atypical antipsychotic, Klonopin, and Buspar.
Keep a journal. Take your husband to the doctor with you. I always take my boyfriend because he knows my moods better than I do. Ask questions. Keep looking for answers. You may not be bipolar, but if you are, you need to know and get proper treatment.
