POTS and the empty corridor

Waiting in the corridor for the classroom door to open is one of the most conventional parts of being a student. Compared to a lot of activities at university, it’s something that doesn’t require much thought. But for me an empty corridor is a challenge. An empty hallway can actually make me ill. Why? Because I have a chronic illness that causes me to be unable to stand for long. This is the reason why I sometimes have to sit down in places where other people would normally stand - like the floor.
