Couple things spring to mind.

The first thing I noticed was the 3 week hiatus kinda sounded like avoidance (a psychological term meaning a way of coping with an anxiety or stressor), which makes me wonder if you were just a bit stressed out by exams/approaching/going back home…can you think of what it might be that's bothering you?

The other thing was that I wonder if you felt OK gaming at uni but that for some reason you feel a sense of shame or something for doing it on home turf?

The whole uni thing can be weird, it was a long time ago for me but you do get snapped from one reality to another when you go back home.
