(Definition from askOxford.com)
Don't you think the word "angst" is so apt in describing the emotions that one goes through no matter how old you are? It is so much more versatile than "anxiety" or "fear", don't you think?
Childhood separation anxiety, teenage hormonal-induced mood swings, puppy love, first love, broken hearts, pre-marriage jitters, maternal worries, empty nest syndrome...it's all so angsty.
