College is the time you learn to make your way and to deal with things like independence, loneliness and rejection on your own. Those types of things will not change magically at another school.
No doubt, as others have said, COVID has made the transition brutally hard. Seek out the school counselors, learn to meditate, exercise regularly, and put yourself out there with the understanding and expectation that it won’t be easy or always fruitful.
Good luck!
