That post really made me sad.
I'm not disabled and neither is anyone in my family. But my relationship with my parents was always bad. I never spent any time thinking about the lives of disabled people because they've always been such an alien reality to me, but I think if you'd asked me think about it I wouldve had the vague intuition that disabled at least had good relationships with their parents because how dependent/how much time they were forced to spend with them. Your comment about the trauma that parents never overcome added a really dark twist for me to the concept of "bad relationship with your parents".
Anyway thanks for sharing
