You are correct, this is ideally what she is suppose to provide... but this is very different than being your mother. A mother loves you, places the needs of her children before her own (part of this is encompassed in therapy, but not to the same extent), and is a part of who you are as a person (for better or worse).

I think it's important to draw the distinction between a helpful, caring, and supportive therapeutic relationship and one that occurs naturally (i.e., does not have a formality or business-quality to it).

I truly wish that you could get what you need from your T ... I know I crave the same things... but the real healing won't happen unless you can take what you learn in therapy, and apply it to your relationships IRL. It's easy to become "stuck" on the idea that your T is the answer.
