ZG for heaven’s sake, you should know by know that you wont be “listened to” at least at the level you expect. I am baffled that this is still a serious thought in your mind.
Your fourth paragraph in message #8 seems like a rehash of the same old same old. What is the point?
I guess, if you are certain that you must attend this last performance meeting, then the above comments from other posters here that focus on you providing a short, bulleted rebuttal seems to be the best course of action.
One thing I would really like to see you do is to have a plan in place for professional support in your new job. It will come with stresses, with challanges, with problems. You will need a therapist, a strong relationship with a good one. You will need perhaps other support professionals. I am not sure that this SImple Living group here is the best place for you to get realisitc feedback since we are handicapped by knowing only part of your reality. I also think you do yourself a disservice by,what appears to me, going to many sources for feedback and those sources may just be an echo chamber for you. That centers you in the hole of misery, I think. Just my opinion.
