I can't tell if I am having major anxiety, or chest pain or both. I swear I am going to end up with a heart attack. I feel so nervous and I feel like there is a walnut sitting in my heart.

I am under an enormous amount of stress, but I have never had chest pains from stress before this week. I am kind of scared.

Should I do anything about it? This has been happening for days, and nothing seems to help. I am afraid to go to the hospital because there is probably nothing wrong, but I am afraid not to go in case there is something wrong. Also, if I go and there is something worng I would be ruining my family's trip to Florida. We leave Sunday.
