My T gave me a stats book worth about $150 while I was taking online courses because she knew I was struggling with them. It was right off her shelf and she said that she had no use for it anymore. I felt kind of bad at first, almost like I was whining so much that she gave me the book to make me shut up? Crazy irrational thoughts, but you know, it happens.

I guess just look at it in that sense that she had two vacuums an obviously she only really needed one. I'm sure she'd do the same to a close friend who needed a vacuum too, maybe even a total stranger. I'm sure the little spark of happiness that she probably saw from you was enough for her, so you don't owe her anything.
