I also am in a similar situation.

I have such difficulty believing anyone could care about me. But I want my T to care. And all her actions shows she cares. Yet something in me doesn't believe it.

Yesterday, I had a long phone call with my T. It was a difficult phone call (I'm in trouble with her and my Pdoc), and I constantly felt like she was punishing, rejecting, or threatening me. Every time I felt like that she'd say: "Scarlet, I'm speaking from my heart. Why am I doing [talking] about this?" And every time I had to repeat: "Because you care about me and are concerned about me." And then she confirmed that's what she was feeling. It actually helped a ton repeating it over and over again. For once I started to believe it. I'm still in trouble, but this time I'm not misunderstanding my T...YAY!!!!
