it depends a lot on your character, but humans don’t necessarily need friends. friends have pros and cons. however, if you are convinced you need a friend: you make them by doing activities, helping each other out or having similar interests. for example, you could learn how to sail or canoe or join a knitting or pottery course. Talk to the other participants. Find out a few things that don’t make them uncomfortable talking about. Then afterwards, you linger a bit and try to find someone to go to a bar (you don’t need to drink alcohol; it’s just for bonding), karaoke or dance in a club. On another day, ask them to go bowling or go to tge cinema and talk about the movie afterwards. There is something in human nature, that if person A helps person B with a small thing, person A will start feeling a bond. So, let them buy you a cola or bring them a funny hat or so to start mutual bonding.
