I KNOW IT LOOKS LONG, BUT PLEASE READ AND ANSWER!!!!!

ive never even talked to these girls before & sometimes they give me dirty looks for no reason & when they think im not looking, they stare at me! ive been told before that its because im beautiful & they’re just jealous. I have long light blonde hair that ends right below my chest(its naturally that color) large blue eyes, & fair skin. The only makeup i wear is mascara & on occasion, a little eyeliner. ive never done anything to make these girls not like me. Alot of guys at school talk to me & flirt with me & i’ve recently been told by 3 guys that they really like me. I get compliments everyday like “your eyes are so pretty, do you wear colored contacts”? (no i dont lol ) or ” your hair is so pretty” of course it’s flattering but im kind of shy so i always blush & get nervous & i just say “thanks”. One time one of the girls that are rude to me said

“you have the most perfect skin, what cover up do you use”? & i said ” i dont wear coverup”, (because i dont, like i said i only wear mascara & sometimes a little eyeliner) well she didnt believe me! she was like “you’re just saying that so no one else can go buy the makeup & your skin will look better then everyone elses”! i was so shocked i just stood their thinking are you kidding me?! So its only these 3 girls that are the problem & for no reason they’ll give me dirty looks. im too shy to go up to them & ask what their problem is, i dont know what to do. i talked to my friends about it & they were like “do you want us to be honest with you”? & i said yeah . & they said ” you dont even know it, but your gorgeous! everyone knows your beautiful but you just dont see it, if you had some confidence these girls wouldnt be mean to you” i was soo surprised when they said that. they also said thats why they stare at me when they think im not looking. Ive also noticed other people stare at me alot. Ugh, i dont know what to do. Should i say something to these girls, or should i just ignore them & not let the dirty looks & rude comments get to me?

any advice is greatly appreciated :)

ps: i dont know if this helps but im 16, & the only people that i have a problem with are the 3 girls, everyone else just compliments me alot, & ive also been told that they’re being like that because they’re mad that alot of guys like me, but i dont know. please dont think im bragging or anything, trust me im not. i really just want some advice or opinions on whats happening.
