She ruined her life. It is discussed she is suffering from lung emfysema... In the last stadium of an emfysema you cannot even blow out the smallest candle. You can slow down the process of an emfysema, but you cannot stop or even heal it.
I'd love to see her getting healthy again, but if the rumours are right, and she is suffering from an emfysema, there is no way left.
She's got a great voice and makes just terrific music. Saw an interview of her on youtube which took place only 4 or 5 years ago. OMG - what a difference. In her past she was sober and had a vision for her future. She thought rationally. Later she was caught punching fans and living on cigarettes, vodka and crack. Time to get a really new lifestyle Amy!
Her split from Blake will help her, I am pretty sure with that.
