Flavia,
I am sorry to hear about your situation. Mine is different, but I did find something that had the positive side effect of putting me in a good mood most of the time. I suffer from generalized anxiety disorder. My doctor put me on series of SSRI's for daily use and Xanax for accute attacks, and will share my experience. I first went on Paxil. It really helped with the anxiety day to day, but sex life went down hill and I started gaining weight. We next tried Zoloft, not as effective but lost the weight but still hurt the labido. We next tried Celexa, not nearly as effective as the Paxil, and still killed the labido. We then tried a non SSRI, Wellbutrin, this made my anxiety worse and I started taking more Xanax which is not good. Right after the Christmas holidays he put me on Lexapro. Helped tremendously with anxiety, no weight gain, sex life improved, and as I realized later, I was always in a better mood. I have not tried the Effexor as some have mentioned and that may work well, but I can attest to the effect Lexapro has had on me. But as any physician will tell you, different people will have different respond differently to all these medication. Good luck, and I hope you find something that will work well for you.
