Of course you're having feelings, you should be having feelings! It's a year and a half of work, of course you're having feelings! And especially since you're not really having feelings about the vid itself right now (and I hope in a year's time, you'll be able to enjoy it for itself) it's lovely that you're getting to enjoy everyone else's enjoyment, the contributions being made to charity, and the feeling of community.

(Hell, I'm having feelings about the vid's reception, and I was only a little piece of the making-of!)

Mostly, though: I'm so, so glad it's feeling like time well-spent for you. :-)
