Do you guys also get sick like monthly

I assume the poor quality sleep really messes with the immune system, because I am sick like once a month. I'm stuck in this constant cycle of getting a fever, recovering, overworking to make up for the schoolwork, cleaning, and work projects I missed while I was sick and then getting sick again. It's exhausting. I just want a decent chunk of time where I am not playing catch up over something I can't control.
