I'm one of those people who post pictures looking for likes, and I will have a bad day if I don't get any.
It really affects you huh? Why do you do that? What do you get out of it? Do you really think something bad will happen if people don't like your pictures?
My friends would think I'm a wierdo if nobody liked my photos.
It is annoying to try to get your friends to like your photos. It would be better to spend your time more productively and not care so much about how many people like your photos.
You are one boring user who doesn't know how to have a good time.
Do you really feel like you're having a good time when you're worried about the number of likes? If you stop doing that to yourself I think you'll be happier.
