Chest Pains / Anxiety

I’m 18. I’ve been to the ER twice and to my family doctor many times. I get chest pains frequently sometimes it’s just a small throb that only comes for a second, other times I’ll get a sharp pain. It comes and goes and makes me very worried I’m having a heart attack or have a heart problem. I’ve had blood work done many times, EKG, Chest X ray. Everything is fine and my doctor says it’s just from my anxiety. My anxiety does cause me to feel many symptoms like tingles, sweating, heart jumps etc. Last night I woke up in the night and got a bad chest throb that came off and on for a few seconds, then I started to sweat and I kept thinking my hand was going numb. Then I forced myself to go back to sleep and when I woke up now I’m still very anxious about it and I’m always scared I’m dying of something. (I just started anxiety pills) Do u think it’s anything more then anxiety?
