I’m 15 I’m still shy I’m anti social I can’t talk in front of large groups I’ve never been to a school dance or party I don’t really have any friends I’m really annoying and kinda weird I’ve never had a bf before and I was wondering if that’s weird or normal bc all my peers and Doing this and that dating and having sex ect going to party’s half of them smoke and drink but I’ve never done either so is there something wrong with me. I’m I lame or something
