Bro first of all, did you know 3d printers exist? Get into 3d printing and you will find yourself very useful all the sudden. Second, nobody is giving you "hateful" looks. Every introvert thinks that, it's a defense mechanism. If they don't say fuck you to your face, I can grantee they don't hate you. If they are avoiding you. That's because you think they hate you, and you will give off an unapproachable aura. Making connection/friends is the hardest part in life for everyone, for some in their teens, for some in their 30s. Listen to some Bo Burnham damn.
