Both are insecure responses to the same underlying uncertainty, but they cope in opposite directions. Anxious attachment amplifies bids for closeness under stress; avoidant attachment suppresses them and retreats into self-reliance.

Anxious Attachment
Anxious attachment is an insecure attachment pattern marked by a strong desire for closeness combined with a fear of abandonment — so reassurance, when it comes, rarely fully settles the worry.
Avoidant attachment is an insecure attachment pattern in which a person keeps emotional distance and prizes self-reliance — downplaying their need for closeness rather than reaching for comfort when stressed.
