I'm concerned whether my impulsive use of the "mommy" title, as an expression of emotional surrender, is a sign of unresolved issues. I currently have a healthy and active relationship with both my parents (holding conversations with my father, and going shopping together and helping raising my nieces and nephews with my mother), and aside from my private, creative life, I feel like I'm still missing an emotional component for myself.

The definition of "mommy issues" appears to be slightly subjective, with whether a missing and desired component of a parental relationship has left you possessive and emotionally unavailable, or touchy and lacking boundaries. Personally, "mommy/daddy issues" seem to be used as a "catch-all" umbrella term for emotional unawareness that depends on an unhealthy perception of others to justify a current mentality/need, which feels too vague.

How would you define and deferentiate a generally immature, emotionally underdeveloped person vs someone who's immaturity is the product of a malformed parental relationship?
