I have anxieties with regards to doing any kind of fitness.

I panic when my heart rate is elevated. I've had everything checked out and it's all good. I can't overcome it though, which stops me for starting. I know the great benefits of exercise, even how it can help with anxiety, but if the anxiety is about the elevation of my heart rate, then I have a fight on my hands.

Has anyone ever heard of anyone who has this issue, and if so what did they do to overcome it.
