I'm unclear as to why her being married and living in the city centre means she doesn't have true problems, or that she wouldn't be able to understand or help you. Has she said something that makes you think she doesn't get something you're going through or are you assuming she doesn't get it because you know a few details about her living situation? From your post, it seems like the latter.

I'm also married (because through dumb luck I met someone compatible) and live in the city centre (because my husband and I have been fortunate to have had decent paying jobs for the last four years). But I've also dealt with depression, lived in a basement apartment with raw sewage coming through the floor, have problems with family, and went through infertility and a miscarriage. You can have both good and bad fortune in your life -- most people do. Is it worth imagining what things you might not be seeing in her life?

You seem to focus a lot on your therapists' (presumed) quality of life and assume they can't help you because it's so different to yours.

I'd really encourage you to bring up the pattern you seem to be in (looking at a therapist's living area and marital status and then feeling like they won't get you/help you). This has popped up in several different posts you've written, so I'm not sure focusing on this particular therapist at this point in time will help. I'd look at what's happening again and again, then bring that to the table for discussion.

I hope that doesn't sound rude or preachy, it's just that you seem to be reliving the same experience over and over.
