“So, I would sit and watch him until he fell asleep. Then I would get up all through the night and had a pattern of wakefulness to check on his breathing and make sure he was okay, because sometimes he wasn’t.

“And, also, just emotionally exhausting because this is a person that I loved more than my own life.”
