If you talk about this with her and it scares her away then that is a very, very good thing. If that happens it means she is not the one who will be able to help you with this, and you need a person to help you with this. If she isn't the one who is able to do that then she is no good to you at all, and the sooner you know if she is or isn't then the sooner you can get on with the business of healing you. It is so important to work with a person who can help, and not a person who can't.
It's just too important to mess around with. YOU are too important to waste your time with a person who isn't able to be the one who walks with you through this. Find out if she can be your person. If she can't, find the person who can.
