Can anyone relate?

So I have heart palpitations all the time. Some days more than others. I don't really ever have symptoms with them. I've been to the doctor multiple times and they assure me that it's normal and I'm healthy, but they really freak me out. They often cause me to have panic attacks because I start to fixate on them. Everyone I know never seems to be able to relate to me. I'm trying to accept that it's normal but it's hard because I don't know any one else who has them. Does anyone here ever experience heart palpitations and it's normal for you? Do you have any tricks to stop them or take your mind off of them?
