this really sucks, billi.
it sounds like (for whatever reason) your T disabled her account, not blocked you specifically.
BUT omg!!!!! that she didn't acknowledge it when she finally wrote.
i would feel crushed.

im glad you're keeping lines of communication open with her. you're being very brave. i hope she can treat you with the gentle care you deserve and explain what went wrong and what will happen to prevent something like this in the future.
