I have struggled with severe depression for nearly 20 years, and have been successful on Cymbalta 60 mg, Zyprexa 2.5 x 2, for about 4 years. All of the sudden, I'm feeling like I cannot concentrate, my thoughts are racing, I'm disorganized, and I'm really super depressed. My doctor put me on Zyprexa 4 years ago, because she thought I was hypomanic. I've always been sort of melancholy, but now I'm paranoid, I keep checking 3-4 times to make sure my front door is closed in the morning so my cats don't get out, and I'm super depressed, fatigued, etc. Could I really be bipolar? My mood definitely needs to be elevated, but how to you achieve that with the meds that are on the market now, and what sort of meds would anyone suggest. Thanks very much.
