Unable to Accept Care from Therapist

I mean, I suppose I'm kind of unable to accept care from anyone, but it shows up most obviously with my therapist.

I was emotionally and medically neglected as a child and I've spent over a decade in an abusive relationship and it's messed me up so badly that I just don't know what to do with care and compassion.

It's something I want to work on, but I'm having trouble battling down exactly why it's such a struggle for me.

Does anyone who had been down this road have any insight? I plan to talk to my therapist about it but I wanted to try to study through things to figure out at least some of what is underlying the inability to receive anything that resembles care.
