That is a psychotherapy cliche, but it has a lot of merit to it.
Significant adults in your life have imprinted/caused MOST of the ways you approach love or work. Just think of how vital those adults were to teach you language -- without them you wouldn't be speaking at all; with other adults you would be speaking a completely different language -- it is the same with your emotions, bounadries and limits, beliefs about yourself and others, how to meet your needs and so much more.
So, do not dismiss exploring your relationship with your parents -- it is the foundation for everything else in your life.
Most of the truths that you hear in a good therapy session will come out of your own mouth. You just didn't know they were in there until the therapist guided you to them.
Try to think of "trust" more in terms of safety. With a good therapist, you can trust that if you share your truth with them, with all it's ugly dark aspects, that they will not use that knowledge to harm you.
If someone is crying, you are getting emotional feedback from that person that they need help. They could cry for any number of reasons but the feedback they provide you by crying remains the same until you discuss it more. Paid feedback or not - outsiders will provide you similar feedback that will be relevant to you because they are able to empathize (that is if you are honest).
But I get you. if you think of paid feedback as fake reviews on playstore, you will get discouraged. It's hard to give a fake plausible review and it's quick to spot for human interaction though.
For you, it sounds like you think that the therapist "might just be doing it because I'm paying them", and that their emotions care towards you might not be genuine? Maybe that you want a kind of selfless care and the monetary aspect would make it feel less selfless or sincere?
It seemed wrong to me at first, too, but eventually I saw how it made sense. The aspects of the relationship that would normally be fraught with fear and uncertainty -- is this person invested in my happiness, will this person respect my confidences, will this person use what they know about me against me, will this person turn against me if they learn my shameful weaknesses -- are encoded in their professional obligations. That's not enough for it to be a great working relationship (you need some personal chemistry as well) but it's a great foundation to start from.
Did you ever consider looking for another therapist?
Therapists tend to get expensive though, when I improve my financial situation I'll definitely look for some more.
I was initially much more inclined to have "here's my habits and behavior patterns, tell me what to fix there" type of sessions. Then I tried to play this game of trust, but the idea of trusting and leaning on someone who sees me once a week to do job and get paid seemed just wrong.
