Hello and welcome!
I am sorry to hear that you are having trouble finding the right med for you...I am sure this is frustrating. :/
I think since you had such a rough start up previously with your SSRI, that trying a new Rx in a different classification is a good plan.
Trusting your P-doc with the initial dosing, and staying positive with your thinking should help you fet the best start on your regimen. I think you can expect a good outcome.
Use our Resources at the top of the main forum page here for great material to work with during your start up. Practicing the suggested exercises daily will make a big difference in how you feel!
Keep posting with us as well if you find it helpful. We'll be here to keep you encouraged along the journey. Let us know how you are doing soon!
