White hairs 😖

Au
I got my first white hair when I was 19. I think it was because I was going through a very stressful time. I dye my hair every so often and now 3 yrs later I haven't been dying my hair in a few months and now I noticed 2 more white hairs. I feel like I'm gonna have all white hair by 30 😂 When did you notice your first white/grey hair??
