Actually, look on the bright side. Eating alone is no problem. If you must find someone to eat with, make more friends. Students who take classes with you can eat together. As for stepping on the spot in class, it depends on which aspect of your orientation is more demanding. Do you put learning first or accept this small abandonment to get along better with your classmates? It depends on your own choice. Of course, you can also find some small excuses, such as your poor eyesight and having to go in and sit in the front row early, to show your cleverness. From what you said, you still attach great importance to the interpersonal relationship between classmates, so it's best not to do anything against the overall habits or cultural atmosphere between classmates. What you have to do is to improve your situation on the premise of being neutral to their behavior.
