I don't want to sound like a stuck record but your T's way of interacting with you does make me uneasy, ie the comment about 'doing what a normal mother would do'.

And as it happens, no a healthy 20 year old in a good relationship with their mother doesn't look to the mother for constant emotional support, but the thing is everyone is different and in different circumstances. A 20 year old with depression will be more dependent on their mum than a 20 year old without any mental health issues. Or any other illness, or rough time, or whatever. That's why I find what she's doing deeply uncomfortable - she makes these little throwaway remarks likening herself to your mother, and does these simple yet lovely and important things for you (like helping with the make up) but what I find incongruous is that that's ALL she can do - whereas, a 'real' mother would go to the ends of the earth for you and lay down their life to make things ok for you. Good mothers fervently wish they could do anything to take away your pain, and would gladly swap places with a beloved child and suffer instead of them.

Obviously, your T cannot (and shouldn't) do that - so it's not fair to play this cat and mouse game with you. I think it's really cruel to make references to being a 'mother' to you, when she is so, so limited in what she can do.

Just to reiterate, I am aware this is my opinion. I'm not saying it's right or wrong for anyone else, and am prepared to be educated on why I might be wrong in my view.
