Can I work at a day camp just to feel appreciated?
Why do you want to work there?
When they listen to my rants about being so irritated at my girlfriend, I feel they appreciate me more
You have the right to work wherever you want to, and if it's a daycare even better because you are helping lots of children. I'm sure they would love to listen to all your stories, but don't go too overboard that they in turn get annoyed about it.
I just wanna work with kids and I don't care if they feel irritated or not.
It's completely fine to work with anyone, even kids. You're free to make your living in any legal way that you'd like to.
