Hi Nancy
I am sorry you having such a bad time with all this. As the others have said, your situation sounds very complex and it not easy for us to advise. One comment I would like to add, though, is that Effexor is one of the hardest antidepressants to get off so some of what you are feeling could be w/d from that.
Having said that, I know of someone who often says "pick a drug and stabilise on it" so maybe that is something for you to consider. Whatever you decide, you will need to wait a few weeks for your body to adjust. Constant chopping and changing, as it seems you are discovering, only makes things worse.
I hope you can find some relief and soon
