Perna raises an interesting point, but I don't know that it would be 'rude to bring it up again'... I guess I don't see it that way. I've read several articles on the internet, by Ts, where the T has expressed hurt at the way some of their clients have left them abruptly - the T is left wondering what they did/what they could have done, they have all these unresolved feelings... I think it might be good closure for your old T as well as yourself if you were to write and explain what was happening for you at that time, apologise if you feel you'd like to, etc.. Maybe she's still carrying it around like you are.

I would definitely talk to your new T about it though - I'm sure she's in a much better position to advise! Maybe ask her how she'd feel if an old client who'd terminated therapy in similar circumstances were to contact her again - if it would make her feel better/resolve things/bring closure, or just stir up old hurt. Try and get her to help you figure out if you want to do this for the right reasons?
