I suffered from insomnia most of my life, so I know what you mean. I didn't have it the extremes my son does sometimes - going days at a time with no sleep when it's really bad. But when I was routinely getting not enough sleep, I was always in a low-level depression.

I had lunch with my son today. I asked about his sleep, and he says it's fine. He said that in general things are going ok, and he really did look well. I mentioned the accupuncture thing to him anyway. I told him we should look into it if his sleep deteriorates.

Different topic: He caught sight of himself in a mirror while he was at the buffet today. He came back to the table and said he didn't want to look like he was down all the time. I didn't tell him, but he usually does look down. His face looks ... not sad, but ... idk ... stiff?
