She said no (and I thought she may have been offended)...

I'm kind of worried because:
1. It is not normal for us to email, as my T has very strict boundaries. Both of us in the past have asked before we sent an email (which has only been like once for each of us in our 3+ years). My T never actually asked to send me this email, so what if she feels that she doesn't have permission and it would be too big of an assumption that I would be okay with it? So maybe she will just never email me the list out of this fear?
2. What if she decides she isn't comfortable with writing the list, but again doesn't feel she has permission to let me know? She has said before that she would do things, and then later told me that she was uncomfortable with it.

I can't contact her to ask. If she is just taking her time making the list, it would seem very desperate, rude, and pushy, especially since I had asked her before if she had forgotten. But what if she never emails me? How long do you think I should wait before I contact her to ask? I know I'm being very impatient, but I'm freaking out because I don't know for sure what's going on...
