I am afraid of sounding like a shill, but the fact is I'm 30 engineer, who has been trying to feel better my whole life through experiments with: ketamine, CBD, various nutrients, various dietary changes, exercise, being more social, meditation. None of them made lasting improvement like sertraline has, I wish I had been open-minded enough to try it years ago.
In retrospect, maybe it was ridiculous to try to find happiness with all methods other than the ones there are best medical evidence for... I guess I was afraid that somehow I'd be conceding there was something "wrong" with me (which is wonk). I was wondering why nobody had ever mentioned this before, and I realized people who use prescription medications are probably afraid to admit it. So I'm just putting out my sincere recommendation out there, as I wish somehow had done for me.
