Re: it may not always be from anxiety
I agree with all of you. It is so difficult for me to distinguish between a harmless feeling and when it's life-threatening, although (knock-wood) all of those times I thought that I was going to die from something and didn't go to the ER turned out to be, I guess, nothing more than anxiety. Another tricky thing I found is that I will feel 'new' feelings, 'new' pains ("I'm sure this chest pain is much more severe and/or different from the last time. Oh no...this IS a heart attack..." which turned out to be indigestion or whatever...). It's soooooo frustrating!
