Lamar Odom's 'overdose' reminds me of my own sister's battle with addiction

Oprah Winfrey has revealed that she was pained to discover Lamar Odom's was found unconscious in a Nevada brothel after allegedly overdosing on herbal Viagra and cocaine.

When talking to Extra at the premiere of Belief in New York City on Wednesday, the 61-year-old OWN mogul said she was 'devastated' because it reminded her of her half-sister Patricia Lloyd, who died in 2003 after a long battle with drugs.

'It reminded me of having to deal with drugs in my own family...It is a battle that you can't win until they decide they want to win,' said the TV fixture.

Winfrey added: 'In my own family we lost that battle, I put my sister through rehab twice, she came out of rehab and went right back on Oxycontin and there it was, gone, dead.'

Oprah said she connected with those close to Lamar - including Khloe, Kim, Kourtney and Kris. The family is at the Las Vegas hospital where the former NBA great was taken. TMZ reported Wednesday he has a 50/50 chance of surviving.

She added, 'I know how frustrating it is because you want to be able to help, you want to be able to do something.'
