My T is about 15 years younger than I am but we have children who aren't so far apart in age so it hasn't been a problem in my therapy. I think middle age and older is not such a difference as being in your 50s and having a T in her 30s.

My T has experienced loss in her own life, and at an earlier age than I have. I don't think it matters, though. A good T is a good T no matter what!

I agree that you should see how it goes, and tell her your concerns about being a caretaker. As my T likes to say, that's grist for the mill.
