Sambora split from actress Denise Richards in March after dating her for
almost a year.
The 47-year-old rocker's divorce from Heather Locklear was finalized in
April and his father tragically died of lung cancer on April 21.

"I think this was a culmination of all these things and finally he realized
he needed to take care of himself. He'd put off everything for so long
taking care of everyone else it was just time to stop and deal with his
issues."
