Yes, I think this is definitely something you want to talk with your T about. It goes to the heart of allot of important stuff, such as dependency, loss, abandonment, self-reliance, conflicting emotions. This is fertile ground for therapeutic intervention!
Given the number of years you've been seeing your T, plus the number of years you saw her twice per week, I don't think what you're experiencing now is at all surprising. And, personally, I can't imagine why she would be weird about it. I would think she would welcome the opportunity to work with you on something concrete that is happening in the "right-here-&-now".
I will add that the financial circumstances that are forcing you to cut back, may be a blessing in disguise. It is certainly possible for one to become too attached to, & dependent on, a therapist. This may be an opportunity for you to begin to achieve a bit of new independence. My best wishes to you, mich.
