The grass being greener syndrome began when grass began being green. (Similar to snow, as a ski-thing)I used to think that everyone else had a picture perfect life and had their shit together.
Best to get used to being in yer own skin and how it got that way.
It can be somewhat easier when ya age, due wrinkles&scars and/or experience.
Being thankful for whatever ya've got dealt helps, and knowing whatever makes ya happier and healthier.
