Thank guys. I just emailed my T and told her we would be switching back to the old system of me paying her (my mom helps me out financially anyways). I told her part of the reason was because I didn't like my mom making "snide remarks" about her which make me insecure about our relationship. I don't know if I should have told her this or not, but it's true, I think that the less my mom is involved in my therapy the better. I love my mom a lot, but I don't want her to be in control of my therapy.
