Good idea to talk to doctor. What are the chances of seeing a psychiatrist? They are much better at finding the right meds.
There's different meds that effect different neurotransmitters. What your on effects serotonin. Might be what you need, maybe more. Might be you need something that effects dopamine like bupropion / wellbutrin instead.
There's meds now that help with both at the same time.
The key is this...even if you can't see a psychiatrist: see your doctor every 4-6weeks until you find what works. Keeping a journal really helps too. This way you can see how the changes in meds are helping or not so you can convey your findings to your doctor who can make appropriate adjustments. The journal wil speed up the process.
There's something there that will help you. I'm sure of it. Keep going until you find the sweet spot. It takes a month for those meds to do its work, so schedule your visits accordingly.
