Hey there, I just wanted to share a resource with you that I found a while back called Wildflower Alliance. They are a super radical mental health/peer support organization that's anticarceral and they believe in being able to talk openly about SI without worrying about it becoming an intervention episode. They have online meetings and a discord as well with a channel specific to being able to talk about this stuff freely, if you ever just want to vent to people who get it. They have warmlines you can call but the discord is just for anyone
Sorry I know you aren't asking for help, I experience SI myself and I fucking wish I had people who I could talk to who wouldn't get freaked out. I'm sorry this world makes it so fucking difficult to want to live
