My health anxiety has seemingly morphed into obsessive behavior. I am terrified of getting the flu. Yesterday I was at the doctor for a shot I needed and one girl who was there was sick (the nurse gave her a mask after a bit). I keep feeling like she probably infected me and I only have a few days left. Rationally she wasn’t coughing and was on the other side of the room but I am like this constantly. I see “danger” from flu everywhere. If I sit in a cafe a usually move around a million times to find a “safe” seat. If someone coughs I freak out. What is the best way to combat these behaviors?
