For some of us making friends is very difficult.

My advice would be to get involved in a group (or groups) that interest you, and be willing to reach out to people there who seem lonely and don't have many (or any) friends. And know when you do reach out to someone like that, or someone reaches out to you, that there are going to be some awkward times, accept that and don't allow them to derail your potential friendships. And having friends also means being a friend, being supportive, helping them move when you really don't want to, and forgiving them for their faults and when they make a mistake.
