Does teaching make you sicker?

I’m a first year teacher. All my life I don’t think I have ever been this sick so often. It feels like I get some sort of sinus infection or stomach bug every month. It makes me feel so guilty calling out when it gets bad, especially on days like today where I started throwing up in the parking lot of work and forced my team to struggle finding coverage.

Is this normal? What do y’all do to stay healthy throughout the year? How do I not feel guilty calling out when sick?
