If your T were in an extremely vulnerable place and had not done the work to achieve reasonable emotional health, she might be able to commiserate with you "yup, I know, I'm stuck in the same rut" but would be unable to help you. Feelings are pretty universal. Your T has certainly experienced pain and loss and loneliness. She can empathize with you and (probably) is in a strong enough place that she can hold your feelings, your trauma and your difficulties and give you stability and perspective.

As painful as it is to you that (as far as you know) she's in a better space than you are, she would be completely useless to you otherwise. "I'm afraid that you cannot possibly understand me" is, in my experience, the opening for a very worthwhile session. Try it.
