I don't really know what is going on either. My T stopped responding to my e-mail as well without saying anything. It is like she disappeared. She did that once a few months ago and I totally freaked out. After that she's been good about responding even if it was just to acknowledge that she got my e-mail and we can talk about it later. So not sure what happened now... how interesting that so many Ts seem to be having issues with e-mail right now! I wonder what is going on in their T world.
I am trying so hard not to freak out again but it is difficult.
