Can anyone out there tell me how they made most of their friends?

How to make friends is obvious; just jumping right in head first into social situations and interacting pleasantly. People who enjoy your company, and see you as a worthwhile individual, will continue the relationship. Now, interacting pleasantly requires social skills. You seem to be lacking a serious set of these skills. And no one could explain these skills to you over the internet. You need to see a therapist if you're having a very hard time interacting with other individuals, or engaging in social interactions. Social skills are very pive abilities most people possess, but are very unaware of them. But it can be taught, but by a professional. See a therapist.
