I accidentally have 2 accounts. One is Noelle.j.1 because it connected to my FB and this is the other one (NoelleJ) Can I either have noelle.j.1 deleted or connected with this one somehow?

Also, when I go to my edit my profile there is no option for me to set a profile picture. What I was told to do was go to NoelleJ in the top left corner then go to "edit my account" and it would be there...but it's not. What do I do?
