That's an unusual situation!

But, OK -- and here I go out on a major limb -- a large percentage of people in therapy probably feel that their T may have trouble truly relating to them because their T came from 'wealthier/more stable/more loving/you-name-it backgrounds.

What I mean is, the sort of story/dynamic that you're constructing here is really probably fairly common. You certainly have something particularly concrete to hang the story on. But I've seen this type of concern in other threads. (And I have it myself, actually.) It doesn't have to be based on a T having accomplished parents, it could be based on anything.

So, I would probably say, don't worry about this too much. Try not to get in too much of tangle about how you are so different from your T that he can't understand you. That's mindreading and predicting the future and projection and so on. Just take a deep breath, and tell your T what you need to, and see how it goes.

Good luck. If you already trust your T and have a good relationship with him, the odds are extremely good it will be fine.
