How do I tell my husband I'm ready to retire

I'm a principal and the last few years have been hell. I'm ready to just not work here anymore. I'm over everything. I'm burnt out. After this school year I'm wanting to leave. The school is dealing with a sexual assault allegation. One of the 9th grade boys accused one of my math teachers of sexually assaulting and now I've spent the whole summer stressing about the school being sued. This boy does have behavior issues but if course we still take accusations like this seriously. I spoke to this teacher and she said that what happened was he was acting out and also plagiarized an assignment and she wanted to talk to him but the class next door was taking a final so she pulled him into the little closet in the classroom and all she did was scold him. I lost my cool and little bit and told her "What is wrong with you? In what world is it appropriate to take a minor into a closet." I reminded her that the school handbook even says to only do side hugs so nothing eyes misconstrued. I told her that she put herself in a position to be accused of something when she took an underage boy into a closet. Especially with no other adult around to at the very least advocate that she didn't do anything inappropriate. She tried to tell me she was trying to keep from disrupting the class next door and I told her she should have went outside the classroom or talked quietly. There is no world where it's acceptable for a teacher to pull an underage student into a closet. I fired her for that. It wasn't me saying she was guilty of what he accused her of, but her decision to do that is inappropriate so I fired her. But obviously this stuff doesn't go away overnight. There is a lot going on. The girl possibly getting sued. I'm just done. I want to retire. I don't know how to tell my husband. My job has me crying every day at this point and summer was nothing was stress. How should I tell my husband I want to retire.

Edit: I just want to retire from being a principal. I make really good money with my job but I'm over it now
