How did your mom fail to meet your needs? In what integral moments did she miss the opprotunity to support and nurture you? I am not asking to pry. I am asking you because I think it will benefit you to open up about these moments in time that so greatly impacted you.

just because your T says that you have trouble between good mom and bad mom doesn't mean that things didn't happen to you that caused this. You should explore Why you think this way and where it began.
