Lost interest in a friend?

Alright...so..My friend is going to see Avril Lavigne in concert and Im REALLY jealous...But I moved away from her so I guess I lucked out...But I wish she woulda told me..I mean we barely have contact any more..And when I try to talk to her by calling...she never has much to say..It appears to me she has lost "interest" in my as her friend....But we only live an hour apart...but the way she doesnt talk to me or seem to miss me makes me feel like I live on the other side of the world...And im not very "social"...my parents worry...im not really going to friends house or anything like that..I go to a dance (by myself) every once and a while...but still all I do is hang around the house...I need to make some REAL BFFs that really wanna hang out with me outside of school...dont cha think? =(
