It´s common to think of a T like a mother, a father or any other important person in our lives. I don´t think you should have to worry as the transference is a natural process and a good T should know how to handle that. Transference is always there to some extent and sometimes we feel it more intensively, like when transference is linked to a loss in life.

To me transference has to be accepted by the T and the T must also accept that the client becomes a bit dependent of him/her for a while and that such transference is worked through.

I don´t think you can or should hide your strong feelings, I know it´s hard to admit it to a T but perhaps you could say something short and simple like "in a way I see a mother figure in you" and then you could wait for your T:s response. I also think that a responsive T is already aware when this happens and that he/she already feels it even if the client hasn´t brought the subject up.
