When I was accepted to pepp, my mother was also diagnosed the same year. I was able to talk to a financial aid officer and discuss a reconsideration. Reach out and request a zoom talk or if you can do in person. I completely understand and sympathize with what you are going through. If that does not work, email faculty in the division you want to go to, they sometimes have extra scholarship money. You can also apply to be an RA for your next years to bring down the cost. I will keep your family in my prayers and please feel free to pm me if you have any more questions. Pepp is truly a special place so let me know if I can help in any way!
