As the saying goes, touch grass. :P

To elaborate a bit more, social networks like Reddit are good for interacting with people you normally wouldn't interact (and give you a small soapbox), but I think it's good to do other things as well. I'd say if it's affecting you that much, it's a sign of being too reliant on that. Take the time freed up to do other things that interest you. Read a book, play a game, go do some exercise, pick up a new hobby, get in touch with some friends you haven't met for a while, etc.
