I understand! Unfortunately, way too well. It hurts when you realize that your T has a private life with a family and you're not part of it. It can make you angry and sad that your T is not your mother, that she has a "real" daughter to love. That's the harsh reality.

But your T also has you, and you have her. She has a special, unique relationship with you that has nothing to do with her daughter. She's not comparing you with her. You are special to her in a different way. Not in a less important way, either. T's have a lot of love to give. It's not "either her daughter or you".

I know it's hard to accept the reality and not the fantasy. You know I struggle with it and that's why I'm angry (at least it's one reason) with my T too. You're not alone.

Crying and being angry with your T makes sense. It's grief, like any other grief. I hope you can talk to your T about these feelings. She will help you with them.
