What in the World????? Who Messed Up BLOGGER?????

What the.....hello fellow bloggers....I posted earlier this morning and got ready to share the post on my Facebook page. When I pasted the link onto my page a photo of people who I don't even know showed up! WOW, what is going on with that? I know that it has been some time since my last post, but I never expected that things had changed here so drastically!!! What is going on and can someone please help this simple-minded country girl deal with and understand what I need to do in order to simply share a post. From my understanding I need to integrate my Blogger and Google Plus accounts and then be reassigned a new blog link? Will I lose everything from my blog? Will I have to start all over again? I am almost in tears right now! Too old for all of these changes....I just need life to remain as simple as possible. I need lots of help right now. Please leave any helpful (and simply worded~no code terms please) advice in the comments. (sigh) :-(
