I know biological adolescence is supposed to last from age 14 to 25. But I'm 19 and I already feel like an old man. I don't have a job and I'm just starting my freshman year of college. In fact, I have never lived away from my parents in my entire life. But I still feel like life has passed me by and my glory days are behind me. I have felt this was for around 3 years already, from age 16 to 19. Is this just part of growing up? Or am I destined to be a sad old man, forever longing for his childhood?
