I’m sick should i become a online student?

I am a incoming freshman this fall and have already completed my orientation and picked my classes. so far 4/5 of my classes are in person and i’m worried because for the last 2 months i’ve been having very bad digestive issues which causes me to have bad stomach aches/bathroom problems and i often feel nauseous and have no appetite. Sometimes i feel better but then my symptoms come back after a few days and it’s been really affecting my social life too. I have canceled so many summer plans with friends because of my constant stomach pain. My parents keep asking me how i am going to do college in person in this state since it has not been getting any better. I am really unsure about what to do.
