If you're happy with your therapist, and if I recall correctly you are feeling much better since you've been seeing her, I think you should be able to talk about everything. The therapists job is to help you, she is not there to give you religion, if she can't get past that then you should change, but in my opinion she's been through this before and knows her job. Give it a try, this is important to you, so it should also be important to your therapist.
And darn if it doesn't work out, come back and complain to us, and we'll all sympathize and tell you to find another therapist !:ghug3
