Yes joannasouras, this happens to me all the time. I worry worry worry and when it gets started it is just a snowball effect. I've been going to therapy and the intern I have been seeing has suggested that I be kind to myself and not do this. I have no idea how that is possible when my mind just takes off. I am convinced that it is just a chemical imbalance and focusing on how not to do that just makes it worse. My doctor recently changed my meds so I am hoping that it will get better once I am at a theraputic dose. Do you have a t or a pdoc?
