I think its sad, she obviously needs someone to crack the whip and straighten her butt out. I don't feel sorry for her really though - there are a ton of celebs who are followed around endlessly and don't reveal themselves, and do all sorts of those behaviors.
For her children's sake - she needs to get help and she needs to seclude herself for awhile.
If she didn't want people to know she shaved her head, then why did she go to the hair salon to have someone else do it?
Attention is attention - whether it be good or bad.....could that be what Michael, Anna Nicole, Lindsay Lohan, Paris Hilton have in common - - they don't care what kind of attention it is as long as they are the ones getting it??
