Anxiety/ chest pains

I’m in high school and I have pretty bad anxiety especially lately. It always causes me to feel so many symptoms. Like sweating, light headed, chest pains, tingles etc. My anxiety is related to health most of the time so when I feel chest pains I always think it’s a heart attack or I have some undetected heart condition. Mean while I’ve made my parents take me to the ER twice and I’ve had tests done by my doctor and in the end he diagnosed me with anxiety and gave me meds. I’ve had blood work taken many times, chest X rays, EKG. Everything is fine. How do I calm down and get the anxiety symptoms to go? Advice!
