I feel your pain. My situation is different & so for me, when I start doing the wrong thing, I step back. I am quiet so as not to say the wrong thing. I take my time. I don't put a deadline on things, "last chance" kinds of words, because that increases my panic & stress.
I try to Truly Let Myself start each day with a clean slate....it's all anyone has & that levels the playing field in my busy mind. I wish you Extra Good Luck with this ...
