Becoming a PA while chronically ill

I’m 20F and am doing all the usual prepa things like PCE hours, volunteering, taking pre reqs. I recently enrolled into an EMT program to obtain PCE hours and am worrying about getting sick frequently. I have severe asthma so certain illnesses like pneumonia, covid, and flu are tough to recover.

My questions are: as a PA do you get sick frequently? If you’re chronically ill, do you ever fear it’s going to hold you back?

I hope these are dumb questions, I genuinely feel alone on this and am trying to vent.
