The boundary is a bit of gray area I think some of the time.

For self injurious discussion, sometimes it can verge on suicidal conversations which is *not* allowed. But it can also be very graphic, which isn't necessarily the best idea. In cases where you know you're going to trigger others, sometimes I've made my own private room. In other cases, if I know I'm triggered by a specific topic or too much indepth information about a topic, I leave the room. Do whatever you need to do for self-care, because you are important.

Sometimes we're not always able to be a support for people who need it, but that's okay -- we are all here ultimately to help ourselves first. We need to put ourselves in a priority position so we learn to take care of ourselves first.

(All of this is in my own opinion, I can't really speak for any actual rules for Chat. I will inform DocJohn so he'll hopefully be able to weigh in with his comments).
