Caveat: I’m a Stoic, and I think about this in Stoic terms. I’m aware that this may bias my interpretation, and you should be, too.
You can accept the past without surrending agency in the present or hope for the future. You must accept that your boss has treated you badly, stolen your wages, condescended to you, &c. You don’t have to maintain that pattern, though. You can get a new job. If that’s not an option, you can plan around it, eg. by documenting the wage theft and abuse and sending it up the chain. If that’s not an option either, or doesn’t work, you are free to just not give a shit. You don’t have to engage with it emotionally at all, you can just think about something else while it’s happening and then go about your day. They can step on your neck but they can’t make you accept it. Only you make that choice.
Good advice I can use! I’ll switch to a multivitamin that includes iron and see if that helps.
