Never hold people that are acquaintances too closely cause some are here today and gone tomorrow. Real friends stick around. Try not to force friendships. It will only bring you pain. Everyone doesn’t deserve to be a friend!

Some "friendships" may seem like that but aren't. You're better off without them

same.

I know. Just replace these trash people with people who appreciate you

I don't think it's you... I think it's more what we expect out of social media sites. Many of us expect "friends" while it's really more of a site to interact with others but not really develop close friendships.
Sometimes, it works out that there is one or two people who become more of a real friend. I hope you find that.
