help

[uboa2]

could sure use some help, I am new to Macs after having owned a couple of PCs, I'm also new to computers about two years, I'm learning more all the time, but have no one to help me so I learned most of it out of a book, I am an older gentleman now retired and have time to play with the computer, my problem on Facebook, up at the very top where I am supposed to write my posts there is a message already there, it says how are you feeling.Paul? Or it says, how are you doing.Paul? It will not post, I can type over it and then delete what I wrote but the message is still there, I can post the message that I wrote over it but when I post the message I wrote over it, the message is still there, pulling my hair out, how do I get it off, I think somebody may have hacked my account and put some kind of virus or command there, can use all the help I can get

Just ignore it and it will go away.
