"Stay healthy, stay home," reads a lit-up sign outside the gates of Princeton University. On campus, the majority of students are gone although a few are scattered around, collecting books and research from Firestone Library, which is in the process of closing. A small group of seniors take pictures on the front lawn, holding an orange-and-black Class of 2020 banner. Instead of a graduation photo, this will have to suffice after years of hard work at the Ivy League school.

In response to the coronavirus pandemic, a growing number of U.S. colleges have already said their campuses will remain closed until the fall semester. Most undergraduates had less than three days to pack up and move out. "I don't think we ever thought we wouldn't be back for commencement and all of those rights of passage markers," said MaryAnn Baenninger, the president of Drew University, a New Jersey-based liberal arts college. "To have that all erased, there's going to be a profound emotional effect."

Seniors will miss their graduations, some juniors were denied once-in-a-lifetime experiences studying abroad and still others have no home to go to and no means to afford housing elsewhere. "The assumption is that they go home to their parents' house, but that's not the case for a lot of students," said Scott Mobley, executive director at the National Society of Collegiate Scholars, a Washington, D.C.-based honor society. "There's a lot of hardship." The honor society allocated dollars from its budget to offer immediate aid for students who are struggling. There were nearly 8,000 applicants for the $125 relief stipends. "The students I'm most worried about are students that don't have a home," Baenninger said. Whether because of an ill parent, financial adversity or other extreme circumstances, more than 200 students at Drew received an exemption to remain on campus. More from Personal Finance:

Stemming international enrollment could cost $41 billion Among students who are home with their families, there is a common sentiment: They love their parents and are grateful as they navigate this new reality amid the spread of COVID-19. But for these newly minted adults, the abrupt halt to life as they knew it is nothing short of heartbreaking. Abigail Sepich, a 21-year-old junior at George Washington University, is currently living at her parents' house in Overland Park, Kansas. But her mom and dad relocated to the state after Sepich started school, so the city is unfamiliar. "I never lived in Kansas," she said. "I don't know anyone here outside of my family. "It's very isolating to not be around anyone my age," Sepich added. "That is the hardest part."
