MICHAEL Strahan’s daughter Isabella has officially begun her chemotherapy treatment as she battles a brain tumor.

In the hospital, the Good Morning America host gave his daughter a sweet kiss on the forehead after she revealed all of her current worries and concerns.

On Wednesday, Isabella, 19, shared a new installment of her YouTube series chronicling her brain tumor battle.

The teen, who revealed her diagnosis on Good Morning America last month, has started chemo at Duke University Hospital Cancer Center in North Carolina.

At the start of the new Vlog, Isabella showed off her “big bag of chemo” as she admitted she’s “terrified.”

“I’m stressing myself out because I feel like everything could just go wrong with me at any moment,” she said.

She said she was worried her leg might just start twitching or her “organs just shut down.”

Isabella’s sister, Sophia, and her dad’s girlfriend, Kayla, both had something to say about her intrusive negative thoughts.

“Can’t you just chill,” Sophia asked.

“Let’s talk positive,” Kayla told her. “Positive thinking!”

Later, her dad, Michael, came to visit with her favorite Chick-fil-A breakfast and gave her a sweet forehead kiss.

Before entering her room, he explained how he washed his hands, wore a mask, and used automatic doors as part of the hospital’s protocol.

Michael only lowered his mask to give Isabella a quick forehead kiss as a hello before putting it back on and giving her her second breakfast to enjoy.

Halfway through the video, Isabella decided to give fans a short tour of her private room, which featured a kitchenette, bathroom with a small tub, a couch, and two TVs.

The teen made sure to note, though, that the televisions don’t have Netflix and that the sound came out of her remote, instead of the actual TV speakers.

At the end of the Vlog, Isabella revealed the large bandage on the back of her head as she got up to take a lap around the floor outside her room.

She said she usually tries to take one or two laps when she goes for her walks.

The 19-year-old and her family stopped for a moment outside her room after Michael spotted a whiteboard filled with encouraging notes.

He decided to pen one of his own, writing, “You got this! Faith & love.”

Last week, Isabella posted a Vlog about getting her port put in ahead of the start of her chemo treatment.

“So I’m getting my port placed today, which is a device that goes on your chest for administering chemo [and] getting my blood drawn,” Isabella explained from her hospital bed in the video.

“All that fun stuff,” she said sarcastically, before adding, “I’m not excited.”

Though her dad wasn’t in that video, Isabella’s mom and her dad’s girlfriend were both there to lend support.
