Hi There....
I want to encourage you to NOT worry about this. I know it's difficult. Believe me I KNOW.
The worst thing is waiting for a reply from T. In future try not to put yourself in a situation like this. I try now, but still find myself sending messages.
It is probably nothing. She's busy, or technical issues or whatever. it doesn't really matter, but 99% of the time, IT NOT PERSONAL, and means nothing.
Just try to keep yourself busy. Think positive about her. remember positive sessions, look at a positive email reply from before, and just try to relax and breathe.
i'm sorry about this, i know it feels terrible, but trust me...its not worth it.
RELAX!!
