I have sent my t a couple of emails expressing concern over some things I felt she messed up on. However, I kept the emails short and to the point because they were designed only to be the starting point of verbal conversations that needed to happen. The emails were a comfortable way for me to get my point across, and, an easy opener for starting a potentially difficult dialogue with my t. I did have good results come from the emails both times.

What is the worst thing that could happen by sending the email? And is that something you can deal with? I wouldn't worry about upsetting your t. If you feel like sending this email is something you need to do for yourself, then I think you should do it.
