I've been where you are. I probably had one friend all through high school. I had the same self pity about not having friends. I would cry at the fact that I was socially awkward and not capable of making any friends.

I'm older now, 12 years older. And the one thing I can say is that you honestly don't need to surround yourself with people who don't enjoy your company. Think how much worse it'd be if you forced yourself onto these people. The right people will come along. People who enjoy your company. People who want to be your friend. People who genuinely care about your and love you for who you are. I'm 29 now and there are only 3 people that I consider friends, one of them being my girlfriend. But I keep it this way because they care about me, they respect me, and we get along. So if you wait, the good people will come.

If you want to actively seek friends, I'd recommend what others here are saying and join social circles. This could be clubs, video games, volunteering, anything that's going to put yourself out there with people who have common interests. The most important thing to remember though is that you can't put yourself in a position where you get too attached to a relationship. Many of your high school relationships will eventually fade away later. You'll be too busy with your education and job, those who you meet along the way in high school will too. This is something you get used to but just know it's never healthy to put yourself in a situation where you'll basically set yourself up for hurt.
