A Rockland County high school senior says he is trying to turn this time into a positive one.

Clarkstown North senior Daniel Kantrowitz published an online letter on theunsealed.com that could help him raise funds for his friend.

He says he realizes these unprecedented times have created a new reality for him and so many others.

"I’m doing my best to try not to complain about anything. I know there's a lot of people out there who have it a lot worse… just trying to make sure everyone's OK. Do my part where I can. And stay safe,” he says.

His letter is raising money for the Familial Dysautonomia Foundation, which is a genetic disorder that affects nerve cells. Kantrowitz is doing it in honor of his friend Jack who has the disease.

"I've known Jack my entire life. He's a little younger than me. He's one of the smartest kids I’ve ever met. He has what they call FD. And he's a trooper. He's one of the strongest people I’ve ever met. So, I really wanted to help out by doing something because this is a super dangerous time for him."

Every time someone looks at his online letter, a portion of ad revenue will go toward the foundation. It ends Tuesday.
