Yay for you for telling someone, confiding in someone, and reaching out!

Just don't stress over it (i know, easier said than done, heh) and I am sure she will ask some questions. You can either answer her openly, or tell her you have boundaries (if you do or want to come up with some) on what info you will give her. She may ask how to better support you... helps me to have answers like those already thought out. =)
