“As parents we spend all the young years runnin and gunnin, just trying to keep up and raise good humans,” the 47-year-old dad began his emotional post.

“One day you wake up and they are almost grown and you realize you did pretty good at this dad thing.”

“I can’t believe it’s been 17 years since you came in the world,” he wrote to Kendyl, telling his girl, “You have been such a joy for all of us watching you grow up and seeing what kind of person you are.”

“Goes so fast! Our 18 yr old daughter goes to college today,” one fan commented, as another echoed, “wow unreal how fast the time has gone.”

Kendyl is one of two kids that Jason shares with his first wife, Jessica Ussery. The former couple, who were married from 2001 to 2013, also share firstborn daughter, Keeley Williams, 21.
