I get it, I am not advocating to live unmedicated or anything, but pretty much every emergency medical experience I have had any contact with in the USA has been so universally painful and dehumanizing that it gives me extreme pause, I would not willingly engage with it.

I'm fine with someone making that call for themselves with personal experience, although doing it in a sound state of mind can be challenging in crisis.

I'd just caution you that it's not a universal experience. As with, say, COVID masking, some people found it abhorrent, and others still voluntarily mask today; some found lockdowns almost fun, others despised even the thought of staying home for a few days.

Statistically, police/committment intervention from calling the hotline is rare, and another commenter linked evidence (https://news.ycombinator.com/item?id=48122550) of significant benefits to balance it.
