Are you annoyed by cheerful people everyday?

I’m mostly a cheerful person and my peers are very annoyed with that. My family likes the fact that I am cheerful but nobody is cheerful 24/7. I get told to bug off when I’m being happy, cheerful and trying to get people to be nice.
Some people seem to be interested in people that aren’t so cheerful everyday than someone that’s cheerful everyday. When I get upset, or angry, some people are thrilled to see me be upset and be the bad guy for once? Why is that?
