if it helps at all, I go through pretty much the same thought process every time my T doesn't call me back. I figure it means she doesn't care, so I'm going to skip my next session, and while I'm at it I'll just quit going all together.

Then what happens is she will call me back the next day and usually has a really good reason that she wasn't able to call me back sooner, and I realize I was torturing myself with thoughts that she didn't care and I had to quit therapy and OMG I'm all alone, what will I do without therapy, how will I ever get better, etc etc, for no reason.

So, don't do that to yourself, ok? Try not to overthink it. Your T cares about you. It's OK for you to need her. It's OK for you to have gotten angry with her, and it's great that you were able to tell her about that. Everything will be ok with you and T.
