Stress is tough, and fall semester is for sure the season for it. Try doing some things to take care of yourself physically. Are you hungry? Tired? Feeling cold or hot? If so, try fixing them and see if you feel a little less detached. I’m a wall, so I don’t need exercise, but I hear it’s good for humans. If it’s deeper than that, or if that feeling continues for a while, it’s a good idea to check in with BC Health Services (bit.ly/BostonCollegeHealth) to make sure everything’s OK, or to chat with Counseling Services (bit.ly/BC-counseling), because stress is a common trigger for depression and other mental health issues which are super-common among students and faculty both.
