How many news stories have there been about six year olds (for example) calling 911 to get their parents medical help? It really doesn't matter what age a person is, like these guys have said, call 911 if you feel you need to. The police show up first and who is going to argue with them, eh? The ambulance follows.

If your insurance pays for it, it's a smart thing to do if you feel your life is being threatened. You sometimes do have a say in where you go (UNC vs DUKE).

In your state, if I'm reading the statute correctly, it's only reckless endangerment to ignore the medical needs of someone if you are under age 16. So why your state thinks that 16 and 17 year olds aren't going to be recklessly endangered, I don't know. You can dial 911 anyway because there are still laws that protect someone in your situation.

I just hope someone in your state will help you.
