I would drop the MC for now. She is not at a place where it will do any good. I wouldn't even go with her at this point even if she agreed. There is a lot of stuff that she needs to do before MC will become useful. And honestly, you do to. You need to be working on detaching, 180's and GAL. There needs to be a cooling off period. You need to process your feelings (on your own). Severe damage has been done to your MR and it can't be fixed by MC right now. In order to fix your M, it is going to take time and patience. You've got a process to follow and it is a process that I believe works. Follow it.
