((((granite)))) I'm sorry you're feeling scared. As others have said, I also get scared before my appts. In fact, I have a bad habit of cancelling appts because I get too scared to go. Then, I end up going anyway and it feels so nice and safe to be there even though I'm talking about stuff I doin't want to talk about or think about or whatever.
I hope you will go and get to feel the comfort of being in a safe place. T won't know anything you don't tell her and you don't have to tell her anything you don't want to. You can just go and be safe there. Then, if something comes up that you want to share, you can deal with it at that time. Maybe what you need most is to just go and have some safe time there.
You could always bring some pocket riders with you

. Maybe things would be less scary with company.
Also, I like your T's breathe in, breathe out print...
