U should write down what u want to tell ur T. Make sure you space it though so one side of paper. That way you can give her a page every time u are ready. This will give you time to cope with the fact u opened up, and have a chance to work through a lil at a time. This makes u feel not so powerless and vulnerable.

I'm doing it right now in fact but I did it wrong. I write too small and did front and back. If u want u can give her all the pages just to get it over with. Then she can get the overall and work from there. If you T takes it slow with u then u will feel better that even though she knows everything now she can figure out her way of taking it slow for u on ur hardest topics
