I was so very sorry for her folks. How awful to see your brilliant and sweet child self-destruct. I was always rooting for her to overcome those demons. I really enjoyed that kid and her amazing voice and talent.
I am very sure she was trying to fight it but addiction is a very serious condition and even the strongest may succomb on occasion. She is no longer is pain, anxiety, under pressure, nor sad anymore. She is now free to fly and be the spirit she was meant to be. God Bless.
