I just got the sweetest email from a student of mine from last semester and I'm just kind of fhdkhfdk about it.
Basically she said that she appreciated how much I encouraged her and was receptive to her questions and always made her feel like her opinions really mattered and everything and that she would not have done nearly as well in the class without my help.  And I'm kind of like "ahhhh I mattered to her!"

And honestly, that is a huge deal for me, especially considering how down I was pretty much the entire semester.
