Rainbow,
I know you're nervous. But it's going to be OK. If you need reassurance from your t that she still wants to work with you, ask for that reassurance. Ask her what she thinks/feels about what you've disclosed so far. Has it bothered her? I'm sure she has heard things like that before, and she will still be just as committed to helping you heal. Try not to imagine the worst. It's going to be just fine. It's a process, and you'll get there.
