This is just my opinion and two cents. If it is true they had already extensively searched the cliffs, then I don't believe she was there the entire time since Saturday. I hate to say this, but I believe she has a mental health issue and possibly self-medicates via alcohol and/or drugs. She could have planned her disappearance, or maybe it was just an emotional impulse, but there is likely an accomplice that picked her up and she has been hiding out somewhere. After seeing the FB page and media coverage she had a change of heart and went back to the cliff waiting for someone to spot her and to be "rescued." Again, just a theory. I am glad she is back with her family and I hope she is able to get the help she needs.
