I actually have not been taking an SSRI, but I have a huge backstory that is way more boring to try to tell - let me bottom line it - I spent about 12 years being told and believing I was bipolar, and was overloaded with every psych med on the market, including lithium. It cost $980 per month. When I discovered that the lithium made my legs tremor so badly I couldn't walk unassisted, I threw every last bit of everything into the trash and felt better than I ever did before. I of course still had deep problems, but the mountain of drugs just lit
everything on fire.
Fast forward to last year, my new GP discovered (that somehow had gone by unnoticed by TONS of other drs) that I had primary hyperparathyroidism, and have probably had it for - you guessed it - about 10-15 years. One of the many side effects of the disease; the problem is tumors that grow on your para glands and screw up your whole body by leeching calcium out of your bones, dumping it into your blood stream, and effectively damaging all your organs, and your brain especially. The mental brain fog, wild mood swings - all typical, and a lot of people like me, by the time they are finally diagnosed with this, have already spent years being treated for mental illness. I had an operation on my neck (that's where they are located), three of the four were diseased (I had a particularly bad case of it), they removed them and I felt like my life was restored almost as soon as I awoke from the anesthesia. So I figured my Bipolar days were history. Until the last several weeks.
I recently saw my GP, who i trust and is a decent dr, he wants to revisit the possible bipolar connection due to the recent panic attacks, possible masking mania or some mixed state. He started me on a low dose of limictal and we'll see what pans out (while he is also letting me have 2 valiums a day to help in the meantime, which is more generous than pretty much any other dr these days, at least around here)
