crystal: Do you have a date for termination? Will you be able to contact your T at all after that time via phone or email? Do you have another T to see when you quit? Someone posted something similar (not sure if it's okay to say names or refer to someone else's thread) to what you're going through, and also posted in the "termination of therapy" social group.
Have you told your T how you feel about her? I'm sure she will understand how hard it is to leave her. I think it's important for you to tell her if you haven't. It's normal for many people in therapy to feel love for their T. It's okay and understandable, so don't feel embarrassed. I have had strong feelings for my T and had to leave her (many years ago, my first T) so I understand your pain. It really hurts to have to say good-bye when you feel you aren't ready.
How is your T helping you get through the termination? If you are going to see someone else, your new T will be able to help you process unresolved feelings for this T, but it's important for you to face it with your T even though it's painful.
