Hi Darlene, and welcome to PC!
Sorry you're having difficulty with some side effects. It's very frustrating to have to deal with, especially if the med is working so well. But, as they say, the benefits have to outweigh the risks. Hopefully something else will prove to be just as effective and let you get back to your normal life.
Don't apologize for venting, that's part of what we're here for, to listen and understand. Many of us have been there and sometimes it's good to just know that people know how you feel.
Hope to get to know you....
