Instead, the Plano High School senior walked across a stage in Downtown Dallas she was told she was not allowed to be on by district administrators.

“There were so many times in the past year where I was like I can’t actually do all this. It’s too much,” said Victoria McKennon.

Victoria McKennon is not even referring to the grief she went through at Plano ISD this school year.

She is talking about the disorder in her lungs that is slowly suffocating her each day.

“That’s the harsh reality of a lot of C.F. patients. They don’t really make it,” said Victoria McKennon.

“She never gave up. She worked her tail off. So I’m so proud of her,” said Grace McKennon, her mother.

After feeling pressure from the community, administrators finally buckled and allowed Victoria McKennon to walk at the graduation ceremony.

They allowed Victoria McKennon to celebrate life with her friends but also taught her a powerful lesson.

Victoria will eventually finish the one course remaining in summer school and receive her official diploma.

“I think in any situation with any kind of stress, I’m going to think back, at least it wasn’t my senior year of high school,” said Victoria McKennon.

The teen plans to attend Collin Community College after the summer.
