So my friend is doing this thing where they take photos of their friends and send them to another friend who lives far away but it seems I'm not included in this? And it's kinda hurtful tbh like I thought we were friends and I guess it's kinda contributing to my moods and then people say I'm not acting normal and it's like wth :/ what should I do? Do they even consider me as a friend? I'm not sure I'm used to not being included in things but people that aren't even as close to them are getting included so it really hurts

Did you ask your friend about it?
Cause maybe the other people asked your friend to do it some time earlier and that's why they did?

I agree with Kisuke, You might not have the full story;;
Talk to your friend about it and ask them about your friendships.
