It sounds like you're in the process of grieving your former T. So it will probably take a little time. As Jane mentioned, it's probably mourning your mom, too. Try to stick with current T for a bit more. Tell her what you're experiencing. Maybe even e-mail her, since she allows that. It will probably just take some time.

Is it possible that, because of the stuff with your mom and previous T, you don't feel like you deserve all the attention and caring from current T? Just a thought...
