Serotonin Syndrome/ chronic long term high serotonin cause of anxiety and illness.

I am wondering if anyone else has experienced several episodes of high serotonin? After nearly dying from the last episode in February, my husband and I finally worked out that all the suffering over the last few years was from chronically high serotonin. After stopping paroxetine for a while to get rid of excess serotonin, I never felt better. This lead me down the rabbit hole of researching chronic high serotonin and the effect on our brains. It seems serotonin is not the happy thing we thought it was. Very few people realise this. I am yet to meet someone who discovered that their brains absolutely hate serotonin like mine...I get enough from daily life and SSRis were making me sick. That on top of taking pain medication tipped me over the edge, leading to 4 years of constant agitation and anxiety. I honestly thought I was dying of something, and spent years researching every possible autoimmune disease I could have. What a waste of time. Serotonin was making me sick,
