So the bathrooms only have hand sanitizer? No toilets or sinks? How do they wash the blood off their faces? Is the water just not potable? And even if you don't drink liquids (he IS drinking animal blood though) you still get water from food. There's no reason for him to be freaking out this much from not having water to drink.
So, I just thought of something. The vampires don't drink water, they don't shower because they don't sweat (what about their hair?), they don't wash their hands (only use sanitizer), they don't flush their toilets. What about washing clothes, dishes, or ANYTHING, huh? Do they just throw stuff away after one use? This whole "no water" thing is driving me nuts, especially since the school had a freakin' swimming pool.
Wow, this girl is desperate. It's kind of unattractive. Also, now I'm REALLY wondering about vampire physiology again. Do they get boners? Because I'm suspecting the main character is about to get a boner.
