Tired to make people happy!

Lately I've been helping people out, since they have asked, Actually I do not have time to do so still I've been kind to do so.
However now I'm getting the blame for doing so? obviously I'm not doing enough!!

I don't know but when I hear that I get fed up and do not feel like I wanna help out anymore, why make people happy.. or try when they always want more?

I think it's becuase of the Christmas season, people are stressed.. but what about doing something YOURSELF!?! (-_-?)
