Long story short; SSRIs are the product of half a century of careful research and not the evil scapegoat you and your preferred cable news channel ignorantly make them out to be.
Then why the Black Box Warning, warning SPECIFICALLY of those side-effects?
Then why does every single television commercial for every single SSRI (including the 'repurposed' ones, like Lyrica and Wellbutrin) contain the same warning about "Suicidal thoughts or actions" (which is part of the same Black Box Warning)?
You said it yourself "...everyone's body chemistry is different so any drug can have adverse effects including but not limited to behavior"
And one of the biggest problems with SSRIs, is that many doctors (particularly those not particularly skilled in mental health matters, but that still have a prescription pad), will, after prescribing the latest SSRI that the cute Pharma Rep. came in and dumped a bunch of samples of, will, after the Patient comes back and says "I don't think this is working, doctor; I feel like I'm not getting any better, or maybe even worse." will, instead of thinking of that Black Box Warning, say "Well, perhaps we need to INCREASE the dose..." Many of them will do that repeatedly, even OVER the max recommended dose, simply because they believe the literature that the Pharma Rep. left with those free samples...
I am very glad that SSRIs worked for you; but they are still far from innocuous drugs, period. Again, see the Black Box Warning.
