You should probably be in therapy yourself, and the T will help you figure out how to handle the stress, and also how to best help your daughter. My own T helped me a lot through my daughters' adolescence -- there were a variety of issues -- one of my kids cut in her teens, and she is in her 20's, and fine now. But I really did need the support of a T to deal with that (and other issues.)

So probably the best thing you can do to help her is to get a T for yourself (as well as for her, of course).

Good luck,
