Same here. I hate it when I go on social media and see pictures of other people's happy lives. Then I think there's something all the more wrong with me - because what nice person dislikes other people's happiness? I don't wish for them to be as miserable as me, but I definitely get jealous when I see peers looking good and enjoying their private pools with their boy/girlfriends. I wonder why I even go on social media!

Sorry to hear that you're feeling this way after dinner with your friend. I would probably get a bit miffed too. But this does not mean that social interaction is not good for you per se, it's just that you've got to choose the type of people you hang out with i.e. someone who won't make you feel even more depressed. I'm sure your friend is a good guy, but maybe he's not the best person to be around now.
