If you related to the feelings of panic and agitation at the prospect of conflicting advice, let me suggest it is amplifying internal conflict. Right? Maybe you already knew this. Probably you did. However, it's taken me forever to learn this lesson.
Stand your sacred ground
A number of years ago I worked as an apprentice at a summer vocal program. One of my duties was playing for voice lessons every day. One of the teachers was intense and mean, to say the least. She would regularly scream at her students, all kind of profanities, and call them stupid, or fat, or anything else nasty. Sometimes she got really physical with them, yanking on their face or jaw or pushing with all her might on their abdomen.
