Rainbow,
I think DBT is going to be a key element in your struggles! You seem to have already sensed that. This longing for your therapist isn't going to go away overnight. That's okay. DBT talks about radical acceptance being the way out of hell and suffering which is where you appear to be now. Also in DBT it talks about nonjudgmental attitude--which includes the judgements you put upon yourself, so you can ease up, accept the T relationship as it is and eventually you may come to love the T relationship with its limits because those limits will actually feel GOOD.
