I think you handeled it well. I would not/have not done anything about it other than be more upset when something like that happens to me. I have called crisis lines before with specific requests for how to help me ground, or how to help me stay safe in the moment. I have had crisis lines hang up on me, citing that they were there for suicidal crisis only (despite the fact that their website and literature all says "any" emotional crisis). I never did anything about it through, just either called somewhere else, or stewed in my crisis alone. It's awsome that you were able to assert yourself in this situation... I'm sorry it came up though.
