Courtney Love
Since Courtney Love was connected to Kurt Cobain, she was relatively well off when he died. She started her own band, Belly, which didn't see much success. The lack of cash added stress to her life, and she relapsed, which then led to her selling the rights to the Nirvana songs that she owned. Nowadays, Courtney Love is doing much better, and she has been sober and successful for quite some time.
