A few years back, right after I graduated from college, I had to be confined because of depression.
In the facility, our days were regimented. We (the other patients and I) woke up at 6 in the morning, stretched for a bit, ate breakfast, did a morning activity that lasted for an hour or so, had lunch, then took a break. We had another activity in the afternoon, and then a quick snack, then a break before dinner. At 9 pm, they would turn off the lights.
During that period of confinement, I got to meet another patient, who was reading a book on Buddhism, which I ended up reading because I was bored with the routines. I remember being engrossed with the part about anattā, which is the Buddhist concept of non-self.
