Kobe Bryant expressed insecurity via Twitter after the Lakers’ 107-102 loss Friday to the Clippers.

"Thoughts of self doubt...Am I done? Is this how my career will end?? I REFUSE to give in to these thoughts. #strongwill #countonchallenges"

Bryant didn't step back from his tweet after Saturday’s practice.

"Everybody has it. I'm human just like everybody else," he said. "I think the way I react to it is probably a little different than anybody else. I don't feed into it. I'm able to face it. I'm able to deal with it. I'm able to roll through it."

Bryant wasn't worried that teammates would see his vulnerable side.

"I think it's good for them, especially for them to know I have those moments as well," said Bryant, under contract with the Lakers for only one more season (and $30.5 million) after this one. "I'm sure they've had them. I don't know how they respond to them. In certain instances, maybe they let the self-doubt get the best of them. I refuse to let that happen."
