Are you sleeping well?
Are you eating well?
Your college life has barely begun, let yourself relax a bit. In hs and most if not all your life before college, (it looks like and it is pretty common that) you have been told what to do and you had a very clear goal (getting into a great college) in mind, once that goal has been achieved, you don’t have a clear goal and your future is suddenly wide open to you, so your feeling of lost I am sure is quite common and very understandable. Don’t be too hard on yourself. Use the college years to find things that you enjoy doing and good at. You have the abilities, now you just need to find some motivation.
Which comes back to my first two questions, if you are not sleeping/eating well, you might be on the verge of depression, which could explain your lack of interests in many things now.
