That is great progress! It's nice to know you've become well and stable enough to handle things on your own, but also nice to know that support is there again for the time you may need it. And there is going to be fear/uncertainty involved with change. Pretty normal stuff.
I don't have a T right now either, officially, but I still have phone contact with my 2nd T, from my parents' hometown. I kind of like not having/needing regular therapy session, but knowing that if there's a day where it seems there is a genuine need, I can call her. I don't feel that I really need to be in therapy right now, per se, and she agrees, but it's nice to know there's somewhere to turn for some support if I need it.
I am on the fence about completely forgoing any therapeutic contact, though .....because I have this fear as I soon as I completely cut loose from it, I might fall into crisis. But I remind myself, I do have lots of new tools that I do know how to use ..... and I want to use them and the RL support system I have as much as I can. And I'll know if the need arises to not waste time; and I know you would do the same.
You'll be fine. I think your T is good, that he really has his finger on your pulse, so to speak, and knows you pretty well and will assuredly handle this in the best manner for you.
