Sounds like you really know the answer. You’ll run into stuff like this living in the dorms. If you know their schedule, stay at the library and study, change when you eat meals, find other friends (it’s college so that will probably happen naturally). It‘s easy to be around someone draining when new to school, looking for new friends is common, and it takes time to learn who people are. But making a few changes to your schedule can help…it did for me.
