I have been having pain on my left side like my stomach and chest off on and on for like 4 months. Sometimes I think its because of stress and anxiety but I am wondering if Im going to have a heart attack. Sometimes I feel the pain of others like this one lady died from a heart attack a week ago.

The pain I feel feels like really bad indigestion and goes into my arm and neck. This whole week I've been feeling nauseous and then suddenly today I started to have chest pain and I was completely relaxed today so I don't know what could have caused it....Help here!!!
By the way this is the same girl who has a blog on this website-Britney's blog I'm just using another username too.
