You are right about Woolsey. That's frightening. Well, we do know a bit about his relationship with his dad, but he didn't actually tell anyone that; we had to see it.

Have you read dr_dredd's "Kate Heightmeyer's Five Most Difficult Patients"? Sheppard isn't actually one of them, but in passing Kate thinks about him and his "mild alexithymia". I had to look that one up: inability to talk about emotions, basically, if I've understood it correctly. I've learned a new word! And it so fits.
