Maybe look at some people around you and pick the person you feel most comfortable around. You may find a way into their friendship group and have a lot more friends!
This happened to me, I talked to a girl in my class a lot and before I knew it, I was friends with all her friends and my friends joined my new group and we all had made a massive group :)
If this doesn't work, join a club or youth group, you'll find people who love the same things as you! :)
find people that you really click with.... and than find more people.... don't hang out the rude people it only make's you look like you don't care who you hang out with and you don't care about you're self just make sure they all treat you right and you may be friends for life
start out by mingling with people. find the people that you actually like talking to.
what the you werid person
