"I’m not doing well. I’m sick."
That's Shaquille O'Neal admitting he's really struggling after the death of his "brother" Kobe Bryant -- saying he hasn't eaten or slept since finding out the horrible news.
"It just hurts," Shaq said on his "The Big Podcast with Shaq" show ... noting that he was already in bad shape because his sister Ayesha also passed away recently.
"I’m just getting over the death of my sister. You guys told me the other day when I came in, I looked like I needed some rest. And I haven’t been sleeping after Ayesha’s death.
