Thank you for the response. Your comment and other ones indeed explain the matter - some colleges are basically their own cities, located near a small town.
My own conclusions from this appalling story are:
1. If you're at a U.S. university and are experiencing mental difficulties - just pay the 25$ copay and see someone outside the university. Had the OP done that, Yale would have probably had no clue what was going on. Maybe someone would notice she's missing classes, maybe not even that.
2. Don't get committed. If you need to, see a therapist on your time and on your own dime. They likely won't order you to take off your underwear, spread your legs, then hop up and down to make sure nothing was hidden “up there".
