okay sure, hehe seems that many people got stuck right at the start.

At the start you need to talk to the hallway nurse and then go to the counter.
once you take the pills from the counter the nurse will clear the path to the hallway, if you follow it you can enter your room, (the last one) and there's a trigger cilinder there, that will activate the next events on the game.

Sorry for not making this clearer heh, let me know :)
