There is a saying which applies here sky-blue:
When a therapist only has a hammer, all of your problems will look like a nail.
When you are holding a glass slipper in your hand and trying to find the courage to put it on, the last thing you need is a maniac with a hammer saying they can help you.
Unfortunately, not all shrinks have the good sense and professional ethic to say: "I can help you with A, or B, but I really am not trained or qualified to do anything for C, so if you will authorize me to talk about your case to other professionals for this purpose, I will be glad to refer you to someone who is better equipped to help you."
