If you are at a point where you want to share, then you are ready. You will never feel ready in that sense. The first therapist I went to did not believe me because I too have a rather strange story, and that set me back. For years I tried to hide it and tell myself that I can't trust people. It got to much and I decided to go to therapy again, the person I went to I did not like, he just didn't have that "tell me all your secrets" feel to him. And then I found someone who was sincere and honest, and if he didn't believe me, he never let it show. He did ask me once how I can be so emotionally detached from the things I tell him, and I thought he was implying that I'm lying. He said that it is a strange story indeed, but the point for him is not to believe or not believe me, but to help me, and therefor he will believe me, even if it's not true.
I never felt like I was ready, and after telling him everything I felt like manure for a while, but it blows over in time. I'm glad that I did tell him, even if I regretted it at the time. If you don't think your T will believe you, tell her this, tell her that's the reason you are holding back. Therapy should not be about "convincing" your T. If you don't feel you can do that, find another T... there are people that will make you feel more comfortable than others.
On the other hand, therapists hear weird stories everyday, so maybe you won't even shock her...
