I got a reply earlier today and got some referrals and also clarified the stuff about my file so that was fine. I asked T why she was closing her practice. I said that I know its not any of my business but that I had been worried about all the possible reasons behind the closure and was having trouble processing it.

This was the response:
I'm sorry to hear that you have been worried about the reasons for my closure. There is no need to be concerned. Regardless of the reasons though, finishing up is difficult and understandably so given the long journey it has been. You have achieved much in our time together and I think that is something to be pleased about. I am confident that you will find another therapist who will be able to see you through the next stage of your growth and personal development.

So I didn't get an answer but it was a nice response at least.
