The hardest thing for people suffering from anxiety and depression is to find the right drugs that work for you.
Try Zoloft along with Wellbutrin as they are very complementary drugs. The fact that a psychiatrist would tell you to find another doctor tells me you didn’t have the right doctor.
Many years ago psychiatrists used to really get to know their patients and that helped them find the right combination for each patient.
Today they just keep trying different antidepressants and really never take enough time in finding out what you are facing.
Hopefully you can find the right doctor. They are out there but not easy to find.
Good luck to you.
