It does sound like it could be panic attacks, but maybe a cycle. Tell us more about how you feel and maybe we can help you manage it a bit. I do think it could be caused by triggers of being home & time of day. Maybe as a distraction tonight try to refocus your attention on finding housing at school that wouldn't require you to come home and stay for long periods. I always thought it was fun to look for places to live and potential new roomates when I was in college. Hang in there.
