my reasons are because i have terrible anxiety when it comes to school, seriously its gotten so bad i tried to kill myself last year (:P) i feel depressed all the time and im literally over eating and under eating all the time from worry and im only in 2nd year! i dont go out at all im the un-healthiest person i know and i spend days on my laptop all the time :P during summer i eat alot better i go on walks all the time i meditate and i feel ALOT better and way more productive i know poeple will say "but its gonna ruin your future" but tbh i feel like i wont have a future if i stay in school and i mean it makes me sick (not a joke like i feel physically feel sick and i got sick 2-3 times cuz of school), i really just want advice (honest advice) i dont wanna live like some drone :P please be honest :D have a good day
