Meaning, she talks about how we all drain her and most days she just wants to run away.
Does she teach in a public school? What grade level? How well does she maintain her classroom? Does she complain about all the stress that's put on her (as the teacher) and that she doesn't have enough time to "teach"?
I could ask several questions related to her job, but to save time I'll just say I think she sounds like a woman who is stressed out. The quote above jumped out to me, b/c I can see her grouping you and the kids......with her classroom kids. You've all become like one big problem. She feels drained b/c her stress at work affects her home life. She is in a bad mood every Monday, b/c she has to go back to deal with her class. She has to deal with parents. She has to deal with the Principal.......and the ton of paperwork. She wanted to wait until the week after her observation was completely over, before returning to mediation. That makes me think she doesn't feel on top of things at work. How much does she talk about it? How much do you listen?
You've described how she doesn't pick up after herself at home. Is that out of laziness, carelessness, fatigue, or a lack of pride? I'm wondering if she has always struggled due to a lack of organizational skills. Someone who has great organizational skills has to keep things picked up and put away. Does her classroom look like her house? I only point this out to support the idea that the root of the problem may not be an unhappy MR, but an unhappy profession. It's one thing to love to teach, but as you well know......it's all the other stuff that can get you down.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
