I'm sure "they're doing it wrong", but these were fully licensed doctors, prescribing drugs in an approved manner.
I'll give an example, I read once that about 60% of people with bipolar disorder are unemployed. It isn't the diagnosis that does that.
So I just read that comment as "they sought treatment and ever since they were a wreck". Seems like the causality could go the other way.
I could imagine that SSRI can activate this autopilot for some people and worsens their negative thoughts.
If the person is correct and not dusional they had a statistically unlikely reaction to the drug- presumably too rare to show up in the drug approval process- and it ruined their life.
While not fun working through the gamut of medicines, some of them finally pulled me through it all. It took almost a year to fully recover with dedication to the medicine and modifications of it and therapy.
If I didn't have a good family and primary care doctor, I guarantee I would have died in some manner unless hospitalized.
People need to realize there is danger to their words. Psychiatry is nowhere near perfect, but people are trying. It is an incredibly difficult thing to understand. But I feel people who speak against medicine have never truly experienced deep depression or anxiety. A panic attack can hit you sitting on the couch, and then by literally doing nothing, your heart rate can reach 200bpm and massive amounts of hormones making your chest and skin feel like it's burning, and next thing you're calling an ambulance because you think you aren't breathing.
