I am so, so sorry you felt rejected and unsupported. Having been a patient in a similar situation--I overdosed and was brought by friends to the ER where I was incoherent and belligerent--I do understand how you feel. It made me reluctant to ever go and seek help again.

Having said that, I am going to speak from the other side. I also work in a hospital ER. I know...I was a patient and also work in one. It's actually the same ER, too. My co-workers have no idea--it was a long, long time ago, and I was probably not recognizable. And I'll never tell them. But the point is that there are a lot of patients who come in feeling the same way you did, and unfortunately not everyone has the same level of compassion and empathy. They aren't, for example, going to treat you like your T treats you. I agree with a previous poster, asking the staff to sit with you is stepping over the boundaries. Not only that, they frequently simply are unable to do so. It really stinks that there was no one who could be there with you; I've been there as well--my support person walked out as soon as I was admitted. But I hope you understand the limitations of the ER: you'll get help, but it may not be exactly what you want or think you need, especially if the situation is getting out of control. And they are unfortunately not there to provide therapy or specific emotional comfort.
