There are some interesting things I think about what you said. For example, you were molested by a family member, but you say you added some details to spice it up. I definitely understand the urge to do that... my parents didn't torture me with whips and chains, but it feels like they did, I've often felt that for someone to really understand how I felt growing up a better story would be that I was chained and beaten relentlessly in closet. Anyways, being molested by a family member IS, on it's face, horrific. It doesn't need to be enhanced, I just want you to know that. Sometimes the actual physical parts of the abuse aren't as damaging as the psychological, which leads to shattered trust, abandonment, etc.

Also, it seems like you might need to know your therapist is really concerned for you in order for you to know they care. I have this as well, but it's gotten better. We grew up in environments where we weren't cared for. No wonder we wouldn't just trust the therapist gives a crap about our story or us. As a child I only felt cared for when someone tried to step in and intervene in my defense, this usually meant they had to be very concerned for me and my wellbeing... Just wanted to point that out.

We all lie. I just watched a TED talk called "Mind Games" where the speaker said one of every three things that's said on average is a lie. As you pointed out, we can also lie to ourselves. This lying to ourselves is rampant. Here you are seeming to make progress at least in admitting the truth to yourself. I would say consider challenging yourself to admit this truth to your therapist. Trust that this issue is also an issue that therapy might help. Something I've learned is that brutal honesty is how people can become intimate and closer, especially when the honesty makes you vulnerable. so perhaps this honesty with your T will actually soften their heart toward you even more. Perhaps your T will just see you as I do, someone who was abused and mistreated, who like so many people is now lost and needing help.
