Comparing UVA and W&M does not work. W&M selectively attracts more high achieving and academically focused students. Most ( especially in-state students) are accepted to both, like my son. He is introspective and thoughtful and feels he is like most of the kids who pick WM, they chose the school because it has a higher academic rigor ( SATs are higher) for accepted students and did not like the party atmosphere he saw at UVA.
Perhaps those types of students are more prone to behaviors what lead to self harm
