I've checked out google and that post on the difference between attachment and transference, however I'm still confused.

I feel like the transference I had with my T was telling me something but I'm not sure what. If I explain it, I wonder if anyone could shed some light on it for me?

I would alternate between idealizing and devaluing T. For the most part, I idolized T but if she ever made an error and I felt let down or invalidated, I would feel excessively hurt and angry and feel that she is withholding or denying me of something. As a result, our relationship was up and down. T said she felt like I was punishing her one minute and then apologizing the next, which I was. I wanted to hurt her feelings and make her feel the way I felt she was making me feel but at the same time I didn't want to hurt her and so the next minute I would be apologizing. For some time, we were at loggerheads. I was angry with T and she was angry with me. She explained it as counter transference and me projecting my anger onto her. At the same time, I was very clingy with T. As a rule, I'm a no physical contact kind of person but with T I craved hugs. I even had the urge to sit on her knee and I'm an adult! T would comply to a certain point and give me a hug but I realized that every time I had a hug, I never wanted to let go and no amount of hugs would satisfy the insatiable feelings I had to be held and loved. As time went on, I felt my relationship with T became more stable. I stopped the hugs once I realized they wouldn't heal me. I started to trust that T wasn't going to withdraw my therapy, as I had feared throughout. However, then the therapy came to an end. It ended with a hug and once again brought back all the feelings I had before, that painful longing that was never satisfied and this time, as T told me how proud she was of how far I'd come, I was torn between feeling that this was what I had been missing my whole life from my own mother and a feeling of suffocation. However, my mother wasn't a bad mother. I was never neglected or abused, I was always fed and clothed and she cared for me so it is both distressing and confusing for me to have these feelings with T. It almost seems an expression of ungratefulness on my part towards my mother when she did nothing but care for me.

I am guessing from the relationship I had with T that I have an insecure attachment style. However, are all those feelings that arose a sign of a good or bad relationship with my parents? I should also mention I have had similar feelings with male authority figures in the past.
