This is so so hard, and one of the reasons a lot of T's refuse to accept gifts from clients. However, can you look at it like this: if you give your doctor a gift, would you expect them to do anything other than their job in response? Of course not. Although the T-client relationship is more intimate, the basis of the relationship between doctor and client is still the same. Since it is bothering you so much, it's important to bring it up and be honest about it. But know that she has no obligation to reciprocate if she doesn't feel it's appropriate.
