Hi Jennifer!
I can't add much to what the others have already said except my additional WELCOME to Susan's.
Many of us have been in the same fix you find yourself in and I hope you'll find as much, or even more, support and help than I have from this wonderful site. I read "True Selves" also and heartily recommend it. It's a bit textbook-ish but still very readable. The whole citation:
Brown, Mildred L. and Rounsley, Chloe Ann, True Selves, Understanding Transsexualism - For Families, Friends, Coworkers and Helping Professionals, ©1996 by Mildred L. Brown and Chloe Ann Rounsley, Jossey-Bass Publishers, San Francisco
ISBN 0-7879-0271-3
Amazon offers new and used copies, I got mine through Powell's Books.
I'll be looking forward to reading more from you and am happy again to welcome you to Susan's.
