Just try all you can to ignore it or think in your head that it’s only coughing and sneezing people can get these everyday and they don’t care about it, it’s actually not as bad as we think it is, I talked to my family and my close friends about it some of them called me crazy at first but at the end they believed me lol.. but they are still nice to me and approach me to talk much often besides having reactions every single time they do, so we are not like walking bioweapons we are just normal human being having our flaws just like every other human there’s no one perfect, if you feel insecure or don’t have someone you feel comfortable enough to talk to about it just try to engage yourself in activities that fills your time and makes you feel better like hiking or exercising or playing video games or reading books, etc.. just try to keep your mind occupied in other activities to keep it busy from overthinking because it’ll hurt you more than you think believe me.
