I want to have my own "bro."

I'm really hoping I'm not being dramatic or excessive here. I feel lonely. I have friends, some of them are from school and some of them are online friends. I have fun with them sometimes, but not very often. What is making me feel this sense of loneliness is the fact that these people, these classmates and online friends have their own best buddy. They have their own duos, their "player 2" or something. When will I ever have that? When will I ever have a best buddy that I could talk to everytime and have similar interests with great chemistry? There was this one moment where I thought I'm really gonna take my friendship even further (not in the romantic way, no) with a friend, but nah, in the end, he did me dirty by searching for some information about me that is personal, and then he proceeded to mock me with them. I just wish I have the kind of bond with a friend that genuinely feels real, the kind of bond that's filled with deep mutual trust and reciprocations. When could I have someone to hangout with and be fully expressive, and they'll do the same thing. But yada yada yada after all that, I've been trying to find my best buddy yk? Tried to chat random people around my age on online medias, made a video trying to search for someone who can be a long-term best buddy. Goddamn this is pathetic.
