Will anxiety kill me if i don't get treatment?

No, but...: No, the anxiety itself won't kill you, and it's important to remind yourself of that. At the same time, anxiety is an independent risk factor for suicide... So get thee to a doctor and get the help you need. Anxiety can be effectively treated with help.

No: Although anxiety may make you feel like you are going to die, you can't actually "die " from anxiety.
