I started taking Topamax for my anxiety this year, and found it very helpful. It's used off label for that purpose and also for depression off label.
I also started back on Wellbutrin, but, the generic version, buprion. I'm on 200 mg. This morning, I started thinking I was feeling good. It's the first time in a long time. I don't know yet, for sure. Time will tell. I know at 300 mg, it gave me panic attacks. The pdoc wanted me to go up to 300 mg, and I didn't want to for that reason. She agreed to wait untill I see her next month. So, we'll see.
I did not do well on SSRI's. Serotonin Syndrome. I never want to take them again.
One thing I want to suggest. You didn't stay on the Wellbutrin very long. Sometimes, it takes time to "settle into" a new anti depressant. It takes between 4-8 weeks for the theraputic dose for Wellbutrin to reach it's potential. I hope you didn't stop before it settled down for you. Just a thought. I know when I first started taking it, there's kind of a "rush" but, it does calm down in time.
Hope you feel better soon.
Shalom!
