What’s it called when you lose the innocence of life and like a veil has been lifted of the reality you’re in (reality sucks and/ or is what you make it to be)

And now that I’m here I’m thinking surely everyone has to go thru this at some point in their life. Since I’m possibly a late bloomer to this 33F I’m reflecting on friends who had say a traumatic childhood that would talk/ treat me different (or we just fell out) with bc maybe I’ve been living in La La land while they could tell I could not relate to them.

Had to go thru a lot of emotional distress recently to get here but is there a name for this? Not maturing or adulting but something specific?
