I think what you are going through is pretty standard. Starting on meds are always a bit of a " omg do i need them " kinda feel. It does take time to see results , Lamictal is a very slow medication to work typically , because you have to titrate up your does slowly.

Only you can make a decision about staying in Therapy and taking medications. My opinion for what it worth is give it some more time.

Its had to have patience when you feel like your tumbling into different pieces. You will read here that many people are in your situation or was in the past.

Welcome to PC and I hope you can find the support and help here that I know I have.
