How do you stop the teacher burnout?

I’ve passed burnt out. I’m dead. I’m a zombie. I should be hospitalized at this point. I’m crying myself to sleep every night. On top of attitude kids and shitty admins, I get paid $2.4k a month and didn’t get my contract renewed for reasons not disclosed to me. I’m afraid of my principal (he likes to yell at me in front of the other staff), the whole school knows I’m fired at this point and doesn’t make eye contact with me. The kids are losing it, too— there’s a fight at lunch almost every day now. How do I stop feeling like DEATH?
