HOUSTON – Tobin Creswell has had cancer three times since he was 11.
He's now 20, and doctors said he doesn't have that much time left to live. He said that doesn't mean his mission of helping people will ever go away.
His brain tumor is so advanced he's lost his hearing and his balance, and his eyesight is waning.
"It seems like every day my life is kind of slipping away," Tobin said.
His mother, Darcy, had to text him the questions we asked so he could respond.
"We're all musicians and he can't hear my voice now. I can't sing to him and he can't hear me. We can't sit and talk. We have to text. It's cruel. It's cruel," Darcy said, with tears in her eyes.
Tobin has been through countless rounds of chemotherapy and years of pain. He was able to finish high school, get his driver's license and complete one year of college but he had to drop out because he got too sick.
Doctors said trying another round of intense chemo might kill him sooner.
"It's just like watching somebody disappear before your eyes. It's horrible," Darcy said.
Although he may only have weeks to live, Tobin's legacy will live on through the nonprofit We'll Get This, which he started at the end of 2016.
"I felt like I needed to make a difference," he said.
We'll Get This is a charity designed to help cancer patients with transportation to get to their doctors' appointments and to pay for parking.
"I know that there are a lot of kids that aren't able to get the treatments and, for whatever reason, their parents have other kids that they need to take care of," Tobin said.
"It's kind of like, you know, ''We'll get this. We've got your parking. We got your taxi service, whatever,'" Darcy explained.
Tobin has a history of helping others. He spent time volunteering at Texas Children's Hospital when he was in high school. So the nonprofit is just a continuation of his generosity, his mother told Channel 2.
Even with his life coming to an end soon, Darcy said Tobin is at peace with everything.
"He's miserable and he feels rotten and he can't really do the things he wants to do and he's OK. And I'm, like, 'If you're OK, than I'm OK. I'm going to be lonesome (but) if you're OK, I'm OK,'" she said.
