>Head to the nurse
Sooner or later, you're going to need to do something about your hand. Might as well make it sooner.
Taking the advice of the student you spoke to, you head to the north end of campus. The Rec Center is a large, circular, two-story building, and is situated right at the very edge of the forest, without even a fence to designate where the campus ends and the wilderness begins.
Going inside, you consult a map posted just inside the building, but as you being walking toward where the Nurse's Office should be located, a debilitating sensation spreads through your body, and you almost collapse. Inside this building, you sense two Ominous Forebodings, one from the Past, and one for the Near Future. Something terrible happened here some time not that long ago, and something is likely to happen again very soon.
These revelations damage your Mental Stability somewhat, but the moment passes, and you regather your wits and continue toward your destination.
Reaching the Nurse's Office on the second floor, you knock once even though the door is slightly ajar, and a warm female voice answers, "Come in."
Stepping into the room, you can see that it is mostly furnished in white, with a number of small cabinets above and below the a counter with a faucet and sink. There is an examination cot sitting against the far wall. The Campus Nurse is sitting in a chair near the counter, and immediately spots your injury, since you have blood all over most of your left hand and sleeve, now.
"That's...how exactly did you manage to do that to your hand?"
-You lose 5 Health (35/100)
-You lose 10 Mental Stability (90/100)
-You recover 1 NP? (23/50)

"But...her voice when she's in pain is pretty adorable, you know?"
