Really bad health OCD & anxiety

Hey everyone. Well today is a bad day, I'm sick I'm tired & on medicine. My health anxiety is at a all time high thanks to this awful chest infection going around causing coughing, wheezing, tiredness. I'm on medicine and I know I should trust myself and my dr but I'm downright scared. Please any advice how to get through these next few days of recovery and avoid panic attacks ...thank you :)
