I wonder what is going on in Amy Winehouse world, why she is so confused and disoriented. Is because of her unhealthy lifestyle or she just has so many problems that she can deal with anymore?

Some witness to the weird scene was talking about it:
"She came out of the house, walked down the drive and wandered around on the pavement for a bit."
"She looked upset and agitated but there was no obvious reason for her to have come outside. It was weird."
