Dr. Gould, I have been diagnosised with generalized anxiety and depression. I was just taken off Zoloft after 7 years and put on Celexa 10mg to increase to 20mg. I think I have a built up a sensitivity to SSRI's. I was diagnosised with post-partum thyroiditis 3 months ago and now am hypothyroid. I take Synthyroid 25mcg every other day. If I take it every day I get horrible anxiety attacks. My symptoms include brain swimming sensation, dizzyness, lightheaded, confusion, feeling stupid. But has long has I take the Klonopin I feel pretty good, but I can tell when it is wearing off. I start to feel horrible. Could this be coming from my SSRI's or hypothyroidism. Any suggestion would be very apprecitated. Thanks in advance.
