My T has told me over and over again I have to let those thoughts in. I have to find a way to deal with them or simply have my brain "Skip over" my thoughts. I'm no where near the point of being able to do that now, but I am slowly working on it. Saying "STOP!" helps sometimes, but not very often. Are you working with a therapist? Is (s)he giving you coping strategies?

To the poster who asked about medication. I am on 150mg of Zoloft which helps with my generalized anxiety, postpartum depression and OCD. I've gone through many dose changes, but I am starting to feel like I finally may be at a dose tat is working for me.
