It's sooo sad but that's the disease of addiction. Whitney's voice coach Gary Catona in 2005 said her vocie was ruined but he worked with her and said by 2009 it had gotten back to 75-80%. But he noticed she started to fall off the wagon again. He said he once left her house and forgot to pick up his keyboard and he saw whitney smoking. She gave him a hug and threw the ciggie behind over his shoulder behind his back. SMH. Whitney needed a full live-in rehab for 12-14 mos. She needed to get rid permanently ALL the bad influences in her life from addictions to enablers and individuals who did her no good. She needed to start anew and rebuild her team from scratch getting rid of enabling family members on her team if needed. THEN she could deal with her vocals. She needed to see larynologist and get rid of any polyps or abnormal growth from years of vocal straining, drugs, smokes. After a few mos of vocal rehab then she can think of a comeback. Sad, she never took that time to do this for herself. Her vocal coach said when ever her vocals improved, she got a new booking and stopped and went back to smoking, vices. SMH. Several rehab and vocal specialists have said the same. If she was really adamant at a coemback she needed to do this for herself. So you're talking 1.5 - 2 yrs off before she could considered a comeback. RIP...
