Michael Strahan's daughter Isabella Strahan is opening up about her brain cancer battle. 

Strahan and Isabella first revealed her cancer diagnosis on "Good Morning America" with host Robin Roberts in January. 

In a YouTube vlog posted on Friday, the 19-year-old model chronicled the latest chapter in her health battle. 

As she pressed ice against her head, Isabella said "everything hurts" while recovering from chemo at home, her first time out of the hospital in a month. 

"I feel like I'm having a heart attack," she said while sitting on a couch. 

Isabella called chemotherapy "the longest journey" and opened up about her health anxiety. 

"I think it just stresses me out because so much could go wrong I feel," Isabella said. "Oh no, my heart hurts. 

hat could mean I'm having a heart attack, or, like, my eye is strained. What if my eyes stop working?" 

In a separate YouTube vlog earlier this month, Isabella shared the "not fun" part of her health journey before starting chemotherapy for cancer. 

"I got an IV put in for this kidney thing… Never fun. Healing from my port surgery… Not fun at all. I now have a wire in my chest.
