So both my parents have covid 19 and are really sick I got tested and was negative. But them being really sick and me not being able to do anything to help it’s really stressing me out, I can’t sleep or eat because I am so worried about them. After stressing about this for a week I started to get heart palpitations and shortness of breath that’s lasted for a few days now. Is that normal symptoms?? Can those symptoms last for days at a time ?
