I saw my GP today because I don't have an appt with my new pdoc until Aug same as you. My GP prescribed seroquel. I take lamictal only right now because I stopped effexor without my old pdoc because he wouldn't listen to me that it was making my depression and anxiety worse. I've been taking lamictal about 11 yrs and several things to pair with it but they would become ineffective.
After reading about seroquel I'm going to wait until I see my pdoc in Aug. She will probably want to do something else so why get started with that? I really don't want to take it anyway. More weight gain and diabetes would make me more depressed. I think this pdoc does a lot of ECT though which really freaks me out. Good luck on what you decide. I just got over yet another major depression but I still want to wait and hopefully have something that's going to work for me.
