I think the big problem is your age. At your age (At least for me) everyone needs to be as badass, swaggin, as possible or you will have no friends, it is even hard to make friends that are like you. My advice is to just be pretty chill, brush what others say off, if they bully you try and go along with it, don't let anyone think they are hurting you and they will get bored and stop, it may take some strength and patience, but you can do it.

Once you get older people will start to grow up and you will make friends, you just need to be social, it may seem awkward at first, but trust me you will look like a weirdo if you don't go out and try to make friends. Which may sound mean but it is true. When I got into highschool I assumed everyone would know each other and I'd look like a loser if I went around looking for friends, so I just stayed quiet. Sat alone. For awhile people that I didn't even know would ask me why I was so quiet (Probably wanted to be friends with me since I am so damn sexy.), and I never could think of an answer.

I think what I am trying to say is try to be more outgoing and talkative. Hope I helped. And don't be afraid to ask this community questions, if you present yourself maturely everyone will have no problem helping.
