Burnout from giving too much

I'm completely burnt out from helping my SO with a party over the holidays. I cleaned for a week, got guest rooms ready, helped with yardwork, got the food organized (did not have to do the cooking, thank god), greeted and tried to help guests I have never met before. I didn't get asked to do most of this but it wasn't going to get done if I didn't take it on. It's two days after and the house is a mess. I'm trying to get the energy to clean it all up, when really I want to sleep for 3 days.

Note, I do not like parties, I am very introverted. This party was not for me, though Id say I did over 50% of the work. But if I hadn't done it I would feel a lot of guilt.

How do you balance between giving a normal persons amount and giving too much?
