Please help??! Facebook problem!?

[Victoria]

Hey ppl so im pretty new to facebook and it'd be great if someone could help me out lol. So I started following some page that had funny text messages and now they are randomly saying i shared a picture of theirs that i didnt share. This is really annoying and VERY embarrassing because sometimes the messages are really inappropriate! now everybody is gonna think i shared these links that I didnt share. There has been a lot, and I check my fb every once in a while and delete the posts that say i shared a link. I tried blocking them and hiding them from my news feed and unliking them, and NOTHING WORKED!!! whats going on here? This is very annoying, how can I stop it? PLEASE HELP!!!!?? Thank everyone!
