T just wrote me a lengthy response to my e-mail. *sigh of relief*

She apologized and said that she WAS distracted by her RL, not only with me, but in general. She said she didn't want to think it was distracting her at work, but it was.
She said that she misread the situation with me today and she really did fail to hear me. She thanked me for writing out exactly how I felt and giving her another chance to "hear" me because she said she DIDN'T hear me the first time. She said that she gets it now, and that everything she said today in session was off, now that she understands how I actually feel. She thanked me for valuing our relationship enough to tell her the truth (even though it was uncomfortable) and to say that I wanted to work through this with her by being honest, rather than avoiding it. She said that taking the courage to tell her exactly how I felt, even when I was scared of her reaction, was the right thing to do and that it will make our relationship stronger from here on out. She said we can talk about this more in person next session.

All I wanted was for her to hear me, and now I feel heard. Crisis over.
