Is popularity really important?

[Anisiaa.]

I am in highschool and I always feel intimidated by popular ones even if I don't have reasons. I know the popular ones aren't bad people because I know some of them and they are really ok but something makes me feel inferior while talking to them. I can't be me. I can't be funny, I can't be in center of attention because I am feeling nervous and I am afraid of telling something because I think I will sound stupid. I am introverted but I am not antisocial and I make friends easily if we have common interests and they are not very popular or very outgoing. I don't have a lot of close friends.
I really don't know why am feeling intimidated by popular kids. I have a lot of prizes at national and international piano competitions. Even last week I won the first prize at an international piano competition.
My popular mates/friends are always telling me that I am super pretty, classy and a good friend (I don't want to sound like a bitch).
I want to be popular but somehow I don't.
And I have two questions
1. Is it weird that I never had a boyfriend (I am 16)? Will I find a boyfriend if I'm not very popular?
2. Are facebook likes important? I have almost 90 likes while the others have 100+..

I know this is long but I really need an answer.
Thank you!!
