Health Anxiety

I’ve always panicked over pains. Recently though I’ve gotten anxiety over it. It’s horrible because I’m only 17 and I feel like I’m ruining my life. I now panic over my anxiety symptoms too. I get chest pains that make me feel like I’m having a heart attack, tingles in legs and arms, sweaty, etc. I went to my doctor thinking I have some kind of heart disease and he did a bunch of blood work and said I’m fine and that he believes it’s an anxiety problem. I just don’t know what to do. It’s making it hard to go out or even go to work. Any advice? Can anyone relate??
