I wish I could upvote the half of this comment that questions the wisdom of seeing good docs as a bad signal, and not upvote the part about not disclosing these issues earlier.

This same question comes up when people reveal abuse (of any kind) or other traumatic experiences.

People need time to process some events, and when you're going through some interpersonal trouble, you may think this (is your fault|will go away|is not a big problem|has been solved).
