Ah...memories...
My .02, thinking the best of them, this is what they are supposed to do, right? If they are getting demanding and impolite, it is lack of respect for you and they are frustrated, their issues/problem. I don't respond to that emotion.
At that type of scenario, I would have plans for that day...leave town if just for the morning for errands. I would NOT put anything in writing about TTATT, unless you are ready for that.
Seriously, eventually they will give up on trying to coerce you, at least the "demanding" part. They will always try to get you back. Be firm and in control when in contact with them even though you feel you are not. That aura about you will deflat them a bit. Just keep giving excuses...it's none of their damn business even though they think they have the "right" to bully you because they have "da troof." The world does not revolve around them although they think it does.
In the big picture...things are changing...you will be losing these relationships. It's what happens, and it's sad, but then again...it's sad JW's created this situation. Good luck. It's tough, but for some of us, it's the only way...we cannot put up with being a fake JW.
