the negative effects of a hyperfocused mind

i just lost a really good, almost best friend over nothing. she is someone who hyperfocuses on uni work. we are in the same program but she seemed to have thought her workload was heavier than mine. she always uses the excuse that she has "too much school work" and that she is "actually working so hard because she's getting a degree". babe...aren't we all? anyways she said i insulted her when i called her out on it and it got me thinking about the negatives of hyperfocusing and making your grades your whole life. too much of anything isn't good. i mean yea i'm stressed. it's called finals week. but is it harsh for me to feel like..."suck it up buttercup?" (i didnt actually say that btw haha). we are no longer friends but isn't the point of uni and adulthood to be stressed and...idk figure it out? i mean that's what happens when you're grown. you gotta figure it out. that's what i think anyway. that's all though that's my rant for the night lol.
