I don't have many friends

My "best friend" chose alcohol over me, my other "best friend" chose her boyfriend over me, my other "best friend" stopped talking to me for no reason (he's popular I'm not so that might have been why) and I'm just not very liked the kids at school. They make fun of me cause I like to read and I maintain a 4.0 (I'm the "nerd" or the "dork") And a lot of kids don't talk to me because I'm country and I love hunting and fishing, at my school being country is just "weird and abnormal". I'm really hurt by all of this, I write songs and I'm trying to use it to cope but I don't know how much it's helping. My guitar teacher has told me my songs and my voice are really good and that I'm going to be famous and all of my old friends will wish that they hadn't left me but right now I'm just beyond hurt
