i'm almost proud to be a loner; i guess it's the whole american ideal of rugged individualism
Sometimes people who need people are just people who need people
There's nothing wrong with being a loner or introverted but only if you CHOOSE to be so. Some people just can't socialize and justify this by claiming they're better off being alone.
I have one friend who can't take any train/bus because if he's around people he literally has a panic attack and can't breathe. His social anxiety is that bad and while he claims he's happier alone, I believe he's sick and needs help, whether pharmaceutical or talk therapy.
as for the OP, you can meet like-minded people on meetup.com or other sites like that. There are groups for every hobby (not enough for weed, unfortunately..)
