Does anyone else feel exhausted after presenting something you like for someone else?

Alright, this is so stupid, but the thing is: I like various things, and I really like to show them to people in my surroundings.
One time I showed a horror movie I liked for my mother, and I was sitting there feeling all proud and stuff - but after she'd seen it, I felt, well, exhausted.
I felt really nervous and worried whether she really liked it or not; and if someone turns out to dislike my interests, I almost take it personally.
I can feel really happy while I'm actually explaining the thing, but afterwards I feel really uncomfortable, as if I were talking much more than I should've done.
I don't necessarily do that, but I always get that feeling anyway.

I recently explained the grammatic rules for one of Tolkien's languages, the Tengwar, for one of my friends, and I was glad to hear that he thought the letters beautiful.
However, once we changed the subject I instantly felt really uncomfortable, and I blamed myself for talking about it in the first place.

Does anyone else feel the same?
