hey this book is a great resource on just this subject -- it's extremely readable and is written by trans and nonbinary therapists. they help you navigate both how to be supportive in a trans patient's journey, and how to know when to step back and not incorrectly assume everything is about gender. i am a therapist and can't recommend it highly enough for both cis and trans therapists!
