Step 1. Don't worry about it.

Step 2. Take a minute to appreciate how you are, always have been, and always will be, your own best friend (And a pretty great one at that).

Step 3. Remind yourself about your own worth - And how it's not just you wanting to befriend others, but also you giving others the opportunity (and privilege) to befriend you. If you can't see yourself as a great friend - It's hard to expect others to.

And finally, just be yourself. You want your friends to be those that see you for who you are, and choose to be your friend because of it. There is no trick to making friends - You just have to be friendly and show others why you're someone they should want to be around.
