Hello,
You have already taken an admission which can't be  changed any more. It's a new place for you so you unable to adjust there. It's fine this is challenging which you will face at any point of time. If you run from it it will run behind you. So face it and try to make possible adjustments and changes as per your need as much as possible. Try to learn which is your basic duty and create your career. Rest thing will change as per time. You just needs time.
Hope it helps!
