I've tapered off of several drugs including SSRIs (which, best as I can tell, did nothing but make my brain feel physically bad). It's not a big deal and it's not like it curses you for life.

The suicide point is completely frivolous because those are broadly cases of people who were too depressed to even try killing themselves becoming less depressed. It's statistically just part of recovering from severe depression that you need to pass through a "band" or stratum or whatever where your propensity for suicide is higher because you need to get a sense of motivation and agency back and getting that back in the context of having just spent all your time imagining killing yourself can result in choosing to act on those imaginings. It's not a problem unique to SSRIs, it's just observable with antidepressants because they are one of relatively few things that can be easily administered and help depression in a significant portion of the recipients.
