when i was 14-17, i called a suicide hotline regularly, though, it was less of a specific suicide hotline and generally more for people who felt depressed (telefonseelensorge; literally meaning pastoral care in german - though, as for as i know, they‘re not paid for their service).
it never helped me in any way but i just wanted to talk to someone since i had absolutely no one to talk to which was particularly rough in this period of my life cuz i just recently internalized the bp at that time (i didn’t stumble upon it in the internet but i felt it intuitively) making me think of roping every day.
the big plus was that you mostly talk to females between 20-35, so you could talk to an „empathetic“ and perhaps attractive foid who would comfort you with her voice alone, even if it’s not sincere (but that doesn’t matter atp). these (mostly 1-hour-calls where i would just talk about all my misery, mostly, since the advice they gave was generally trash) calls were the nearest and probably most intimate experiences i had in my teenager (and maybe entire) life. rarely, i cried as well, which was nice retrospectively cuz i generally can’t express my dismay (i wish i could cry more) & just have this flat chud expression.
but i also had a few occasions with people on the other line who would basically insult me, unironically. up to this day, i remember this old (maybe 60-ish) lady that laughed at me when i told her that i was bullied for being ugly; she straight up said that people don’t care how u look like & it’s just my fault for being harassed by normies. she even hang up the call after like 15min telling me to „man up“, essentially.
tldr: honestly, just call them at least once and give it a shot. it won’t make your life worse than it already is
