I'm sorry that you had such a frustrating experience.

I don't use the chat, but that said... everyone is allowed to make their own chat rooms and sometimes you just need a space where you don't talk about what's bothering you - it can still be a very supportive room. They have every right to use the chat portion of this website, as do you. But your needs do not trump theirs.

No matter how you were feeling, you don't really have a right to snap at others and take out all your anger on them.

The mods jobs are to keep things peaceful. They aren't counsellors or therapists, so their role was to give you warnings. They could have banned you, but they clearly felt empathy for you as they just continued to give you out small warnings.

There are always other places to go if one place is making you feel frustrated. I'm not sure what it was you needed to talk about, but there are lots of support lines that you could call. You mentioned living in a group home, so I am sure that someone there is qualified to help you and would be able to listen.
