This site is not a community. There's no way to talk to other people here. That's a deliberate decision, because building a community composed mostly of unusually vulnerable people is pretty risky and I don't feel equipped to keep everyone safe. It's unfortunate though, because it's so frustrating not being able to talk to anyone about something like this. I don't have any good answers to this one I'm afraid.
ElsewhereThe National Self Harm Network forum may be worth checking out, if they're accepting new members at the moment.
