I liked the transferance explanation. I have always found it easy for me to know the difference. I usually recognize the one by the fact that I am responding emotionally to the person as if they are my step-father.
As for attachment issues, I think we get those because our T's satisfy a lot fo psychological needs. This makes us feel more intimate with them than with a lot of other people. I suspect that you may find that you still have some strong psychological needs. The last time I saw a counselor, I didn't hardly miss him when he terminated sessions. Now, I find that I like to play his old tape just to hear his voice. I miss him because he fulfilled psychological needs and my strange compulsion for a counselor is really strong now. Perhaps, you could try to find a way to fulfill some of your pschological needs here, pretend therapy sessions in your mind and other techniques that you have been taught.
