My younger sister is so much more better than me.. and I'm not joking. She is WAY more popular and prettier than me. While I sit home, she is out at the movies with her friends. ALL the guys like her and only one likes me. There about 12 who like her.
For once in my life I want to be the one everyone likes not her.. just ONCE!
Help!

I know it's hard, but ultimately you need to learn to compare yourself to no one else but you. If you assess the value of yourself based on how you perceive the value of someone else, you will never be happy. Pursue and enjoy your own interests.

Even though it might seem like she has more and does more, you can't assess the value of the individual things that she has. It could very well be that the friends you have are stronger friends, the guys who like you could connect with you better. It's just impossible to compare.

I understand how you feel.. it's a defeating feeling.. I felt like that with my little sister too.. I feel that she's way prettier than me and (I don't care anymore about the friends thing, because she grew out of the popular thing) more talented than me.. but I try to tell myself that it doesn't matter and that I am attractive no matter how attractive she is.. it's hard I know, but just understand that everyone is different, and you will find that person who likes you for you and won't like your sister one bit.. it happened to me..

You only need one boy at a time to really like you. More than that is distracting and possibly a real problem. Think about it. She may seem to get more attention, but more isn't better, it's just more.

You only need one good guy at a time. The rest is just a chance to mess things up.
