If after three years you haven't made any progress in your life or whatever you first went to therapy for, it seems like maybe it would be worth seeing what your other options are.
But it's also worth talking to your T about what you want to get out of therapy that you're not. Maybe it can change if you ask. Or maybe now that you feel more open and comfortable with your T change can happen faster. If she just found out that you self-harm then you must not have told her that before.
