College struggles

I started my first year of college this year and it wasn’t so great, I ended up dropping one class and barely passing two classes the first semester and dropping two classes, barely passing one class and failing one the second semester and I don’t understand why I went through this when I was all A’s and B’s in hs I’m starting to think maybe I’m not actually ready for college and I should’ve taken a year off instead of going straight to college. Has anyone else felt like this before?
