Hi, I'm 15 Years Old And For A Few Hours

Hi, I'm 15 years old and for a few hours now I've been experiencing chest pain and throats pain when I breathe. And just 2 days ago I was short of breath for no apparent reason. I do have asthma, but this is different. It hasn't gotten worse since it started, but it hasn't gone away either. I appreciate any help I can get. -Thank you
