Big hugs to you my dear! I'm so sorry you went through that rough period.
Through my research, I've determined my therapist has to have come from money. He dresses modestly, and drives an unimpressive car, and has never made me feel inferior--although I will admit my husband and I do fine financially (neither one of us come from money, though.) I mentioned to my therapist once how my sister in law is on an income based repayment (IBR) plan for her student loans, something I've dealt with quite a bit since I work in finance. My therapist had totally never heard of IBRs and I had to briefly explain what they were. This shocked me since almost every borrower I've seen with a doctorate or with a medical degree is on an IBR for their $100k+ in student loans. (My SIL never finished college, just took out a lot of loans for a non existent degree.) I really wanted to ask my therapist--how much money do you come from that you have a doctorate and seem unfamiliar with student loans?
In researching my therapist I also ran across his home address (hey, I work in finance and look up tax records all the time--I'm not a stalker! Haha.) He has a nicer house than me and lives in a more upscale area of town. But this doesn't really bother me, I wouldn't want to live in his snooty neighborhood anyhow.

My therapist also has a second child on the way, I think both children were through surrogates. If my estimates are correct, it had to have cost he and his husband $100k for each kid. (This just makes me sad what same sex couples have to go through for a family.)
I could see this would be a tough subject, and like other biasises I would hope a good therapist would be aware of how they might be perceived and adjust accordingly. Beyond that unfamiliar knowledge with student loans, the money thing has never come up. My Therapist and I share a strong work ethic, and I know that helps me overcome any feelings of inequity.
