Does anyone else have heart palpitations?

I have them every day, and it is really scary. I feel as though I'm the only one that has to deal with them. I have had tests done and checked out fine, but I get them mostly when I'm working, excited, or full. I want a baby so bad, but I don't know how I can manage one with such bad anxiety over getting these palpitations. It had been about 4 years of having these and I'm just now starting to freak out about them. I don't want to just drop dead one day. I need reassurance or something, I'm too stressed. Anyone else get these? Will they ever go away??
