how do i become that person everyone loves so much?

i don't know but i feel like no one LOVVESSS me. i want to be that one girl who everyone just loves because of her friendly personality and her charm and all that good stuff. but i feel like im not. people tell me they love me and that im awesome but i feel like not enough. i don't want to be POPULAR, no that's not what it is. i mean maybe a little bit,but not completely. i just want to be that awesome person who just gets everyone to like them somehow. i've never felt this way about myself before but lately i feel so bad just because i can't manage to get a good grade in this one class (i know that's stupid, but it just makes me feel like an idiot), i just want everyone to love me. how do i be that girl who everyone loves and wants to be friends with and be around in general, the girl they trust. yes my friends rely on me for sooo many things and rely on me to hold secrets and everything but i dont get called pretty everyday like my one friend or i love you friend like my other friend. i just don't know anymore.
