Why are people so rude and family too

Have you ever encountered some one so rude that they just started screaming at you out of nowhere!?! Well yeah I encountered this kid in my school he was chill and everything untill time passed by he would but make fun off and hurt people it gets annoying. And he makes a kid bleed hella wild with the bite .

(Now family)

I was putting my usual clothes and my aunt told me my hair looked horrible what's the fuck. Like huh!?! Just because it's not your usual hair style doesn't mean it's messy plus people style there hair like that and I at least take of it!! Also my family is very hypercritical and everytime we known something is wrong with a kid or something like autism or ADHD clear freaking signs they always say he or she is just a dumbass and it's nothing. They also like to manipulate and boss around,like yes they would say "back in my day I used to dress up blah blah blah" and say my fashion taste is poor BRO WHAT like bro it's not back in your day okay!?! Not everyone is gonna agree on one style!! They also don't actually care for echothers well being!! They are just two faced and they are so nosey and racist!!!! It sucks so much to be uj thus family even when my mom knows I have depression she calls ut lazey ness okay but i just Wana rot in my bed and think about my life but I feel like shes picking it up lately the only good part is my mom and sister, I wanan hurt myself bc of my aunts and uncles they don't actually care for anything I cwnt wait for it to all be over to finally be free
