Here's my anecdote if you are interested in hearing more.
I saw a psychiatrist at the medical center of my university. I was only on these meds for about 6 months before I could tell they were awful. Abilify and zoloft. Every month, the psychiatrist asked me how I felt on a 1 to 10. I was generally feeling 3-5, as closely as I could estimate that metric in our brief appointments. Each month he doubled my dose of each.
I felt more and more awful in those 6 months, but I just felt less of everything. I definitely became more insane during that period, wildly psychotic. I had always been extra sad, but never completely psychotic like then. I was awake for 70 hours at a time, asleep for 15, bipolar mood swings, unpredictably aggressive. My dick was numb whenever I got laid, and luckily at the age of 23 I was staying hard very easily. Now, not so much.
I'm worried that if I would have taken those drugs, and twice as much of them periodically as advised, that my brain would now be completely broken. As it is, I hope I don't have too many long term damage. My dick is fairly numb in general, but I am still attracted to my now fiancee and have a fair amount of motivation/competitiveness to succeed at work and achieve personal goals through hobbies.
I think SSRI's are the next prescription 'oops' epidemic, and will be much worse than the painkiller problem. The very basic instinctive desires that our bodies pursue as means of existing and living our lives are obliterated by these drugs. I can't say for certain that no one should ever take them, but there are probably way too many people taking them.
Exercise, sunlight, counseling/therapy, a healthful diet that resembles paleo and/or any of the diets of nutrient dense foods with as few artificial ingredients as possible, and plenty of sleep should really go a long ways towards helping the vast majority of people with mental health problems.
I almost think that the people that would really really need these drugs should have a panel of justifiably sane advisers or some sort of joint legal-medical counsel help them decide if it would be better to end their lives. It seems to me that if you take these SSRIs for too long, there would be no way that you would have a fulfilling life without something as powerful as them to numb your existence from the lack of enjoyment, or even desire to think about or obtain enjoyment.
