I’m 20 Years Old And For The Past Few Years

I’m 20 years old and for the past few years I’ve randomly been having what feels like heart pains , I could be brushing my teeth or simply laying on the couch , driving , working , whatever I am doing it just randomly happens , and it hurts to breathe , it slowly subsides after a few minutes or so , but it’s been happening a lot more frequently now and I’m beginning to get nervous , any ideas on what it could be . :( thank you
