Why my character sick and panicking in my bus base

Got a bus base setup and getting it together fine but now my dude is sick,panicking, and severe head pains. Got a generator , BBQ grill, and nothing else that's really hazardous. I do have a bunch of dead zomboids outside the bus that I haven't burnt yet . Please help because I don't want to die 5 days in my playthrough.
