This is more or less how my youth went on the few times my mom would be included in my therapy. Once we finally got to a period where we weren't fighting, then the guilt/shame started setting in because I just never got "better" despite her always being there.
This is most certainly a plausible scenario unfortunately. They take it too personally and feel attacked at their parenting because you're in pain. They can especially feel blamed when they feel they've provided such care, despite leaving out the emotional care that you may of only wanted in a lot of cases. Parents often give what they didn't have to their children and overlook what that specific child actually needs. Some aren't capable of giving more because they never were cared for properly. I think a lot do the best they can though. That's apart of the tragedy of mental illness, just not being able to "help"
enough even if you actually attempt to.
It's a multi-factor problem imo. Created by the perfect storm. This will lead me down a Darwinian road saying CTB is nature's way of keeping the species alive and thriving
