Hey K! Resentment is a big, big hurdle to get over. I think it is healthier for you (regardless of your M) to find a way to work through it so it doesn't consume you. Of course, that is way easier said than done.
You used to talk about closing circles...maybe you can close some circles on that anger/resentment as time goes on? So that when those feelings rise up, they can be a little less intense gradually, over time? Kind of like waves, after the high tide they keep coming, but smaller and smaller ones? Maybe I am not making sense, the time change has me a little out of sorts!
Take care of yourself always...I am going to go get my nails done today. Have you done that lately?? Trying to come up with a fun color...
