Its controversial I have read but all of my pdocs have been fine with my taking an antidepressant alongside my mood stabilizer which I have done since diagnosed 7 years ago, the antipsychotic was added 4 years after my diagnosis. I would give your lamotrigine a chance to work but if you are still not feeling well talk to your dr. Finding the right medicine is a process, it's hard to do but try to be patient. If you go to therapy that can help too. I hope this helps some.
