^those are definitely great questions to ask yourself.
Also, have you talked about this with your T? Maybe you could cut back to once every two weeks, or even once a month. I think that it is a good idea to continue going to therapy when your stable, because it gives you an opportunity to work on smaller things, or things that you haven't had time to talk about before because you were focused on the immediate problems at hand.
However, I understand the money aspect, and if you don't need to be going once a week, then you shouldn't spend the money for that.
