After being removed from Family Sharing contacts are missing

My father had just removed me from the family sharing, and all of a sudden I am missing contacts, they're just gone. And some contact names are changing back to what they were last and it's just really confusing to me on why all of this is happening. I changed my boyfriends name in my phone about a month ago, and now its back to what it was before I changed it. I did the whole log into iCloud and restore contacts thing, but the contacts are still missing, what do I do?
