I also think this should be between you and your therapist. And no one should have to stop abuptly, that's so hard! It should be talked about for a few sessions at least before ending. That is just my opinion and what I would want.

You have a lot of questions and concerns that could be sorted out in therapy; also finishing school is a time of adjustment and therapy can help with that.

If you don't want to end, tell your parents you don't want to and tell your therapist what is going on so you and he can talk about it and about when therapy should end.

You are of course special!
