I want to be by myself but I don’t want to be alone

If that makes any sense. Being around people and trying to socialize is so difficult. I never know what to say and I’m always afraid of saying something that could be taken the wrong way. I also have niche hobbies and music tastes so its super hard to relate with people. All of those factors combined has condemned me as “the quiet guy” in every social situation. Honestly I would just love a friend that is equally as socially inept as I am. We could watch YT videos and do nothing while rarely speaking to one another. We could just be satisfied with each other’s company.
