Alex Trebek, the legendary host of Jeopardy, revealed back in March that he is battling stage 4 pancreatic cancer. He has begun to undergo aggressive chemotherapy treatments to fight the disease. He spoke about his experience on Good Morning America with Robin Roberts.

“I have a good day, and then the next day for no reason that I can fathom it turns south on me,”

Trebek explained that depression and weakness are common for him following treatments. “Surges that come on suddenly of deep, deep sadness, and it brings tears to my eye — I’ve discovered in this whole episode, ladies and gentlemen, that I’m a bit of a wuss,”

He would like to be open about his experience so that others know they are not alone. “Chemo affects people in different ways, and people have to understand that. And there’s nothing wrong with saying, ‘Hey, I’m really depressed today, and I have no idea why,’”

Jeopardy finished filming for the season, now Alex will dedicate his time to his health before returning to the show this fall. “I just have to get strong. As you know, the chemo takes it out of you,” he explained.

“I feel so weak all the time, and that’s not a good place to be.… Hopefully, everything is going to turn out well, and I’ll be back on the air with original programming come this September.”
