I work with 5 of THE most negative people in our district. They tease me constantly about being in my own little happy bubble. Try the positive outlook. I have a daily mantra that I tune into when they get on their negative diatribes....I love my job, I love working with these kids, my kids are capable of anything. I find that when I am convinced of these 3 facts, my classroom issues disappear.

btw...happiness and positive energy are more contagious than negative energy.
