I’ve enjoyed two weeks off from both work and school, but that is coming to an end...

School has started back up, and now I’m remembering what anxiety feels like. Online classes still suck, and I don’t like my current instructor. I know I’m working hard to not be a pain-in-the-ass student since I’m a teacher myself, and when I get feedback that goes against my own training, knowledge, and undergraduate- and graduate-level writing experience, I want to scream at her and tell her she’s wrong...but that’s not to my best interest. I’m also a perfectionist, but at 30+, I’m trying to get to a place where I can accept a B in my life because 1) why should I still care at this point in my life? and 2) stressing over trying to please the nitpicky whims of this instructor stresses me more than it should. After two weeks of literally doing nothing and feeling blissfully unburdened, the moment I started interacting with my online instructor, I could feel my heart rate quicken. It’s not worth it, right? Will any employer care about my GPA?
