"Thinking about math or science for a few hours energizes me, but doing the same for social issues wears me out." I feel exactly the same way. I can't tell if this is an introvert trait, or whether it arises from the kind of problem your mind is attuned to solving (perhaps both). Reading social news makes me pessimistic for the future, and feel more withdrawn from the world. Reading about mathematics or science excites me, makes me more optimistic for the future, and makes me want to engage with as much as possible.
