I went off Effexor suddenly when I had a nervous breakdown in August of 2015. I was diagnosed with MDD and Complex PTSD years ago but since that breakdown, I have also been diagnosed with GAD and SAD. I have terrifying panic attacks now - shaking, rocking, terrified out of my mind. I know Effexor works on the amygdala part of the brain - the fear center - and I have had some anxiety in the past but never like this.

Is it possible that coming off it suddenly could have triggered the panic attacks and constant anxiety? If that is the case, is it permanent?

Any advice you can offer will be deeply appreciated. I love my psych but his only answer is Xanax and it makes me constantly sleepy. Thank you!
