(not really related to therapy but ..)

So this week, while I was in class, I got a notification from eBay on my phone that said an item ('The Princess *****face Syndrome' book) had been shipped. I share the eBay account with my mother, so I knew it was her who bought it.
Get this - the book is about raising highly sexualised, rebellious, disrespectful adolescent girls. The problem? My mother doesn't have a daughter like that (I'm the only girl).

I'm furious. I contemplated how to handle it with her (she has multiple narcissistic qualities, I'm the scapegoat), as any contact I have with her right now is either overly sweet (on her part, she's overcompensating) or tense and/or heated. I can rationalise that she's bought this book as a way to reassure herself that I'M the problem in the family; not her.
I stopped myself from emailing T about it, reasoning that I can't always run to her with my problems because SHE'S NOT MY MUM. And then today she walked past me in town, smiled and said hello.
My heart just .... cracked.
Why was I given such a heartless, cold, insight-less woman as a mother, and this beautiful, talented, kind woman as ONLY my therapist?

Does the transference ever do away? Will I ever be able to accept that T can't be my mother, and that she can't be my "good enough mother"?
I'm so hurt and lost, I don't know where to turn or what to do.
