First of all Screenager - love the cat! He/she is gorgeous! What a face!
I frequently write stuff down for my T, but then usually end up reading it to him. Funny, I know that sounds the same as saying it out loud, but it's a little easier for me that way. I get my thoughts in order on paper first so I don't forget anything. And somehow reading something makes the hard stuff easier to verbalize. I also frequently get my feelings out in emails, which he always answers, then brings up in our next session.
Congratulations on the email to your T, and good luck!
