My friend overdosed and I saved her... but I think she hates me. I don't know if I did the right thing...?

My friend's boyfriend just broke up with her, she has an eating disorder, and her family doesn't care about her. Her ex boyfriend is telling her family things like how she skipped school on Friday and telling them lies about her hooking up with his best friend, and her family is taking his side over hers. She hates her ex boyfriend and was crying hysterically and they invited her ex to their house while she was on her way home. Once we dropped her off her ex threatened my boyfriend and I and just acted crazy. She told me she took all of her pills (celexa and rispederal for depression and mood swings, that's what she said they were), so I called her and asked how many. She couldn't talk because she was in front of her sister, but I asked her if she swallowed more than ten and she said yes. My boyfriend and I called 911 and they took her to the hospital but she got baker acted. Did I do the right thing? She already has enough problems and I feel like her family will hate her now
