Jenelle Evans says she's experienced post-traumatic stress disorder since her road rage incident in the spring.
"Ever since then, I've been having PTSD; I've been having nightmares," she told host Dr. Drew. "When that incident happened, I didn't even leave my house for the first two weeks."
The July 23 episode of "Teen Mom 2" showed footage of Evans and her 8-year-old son, Jace, during the incident. The pair were driving when another driver tailgated Evans and cut her off on the highway.
Evans followed the driver to his home to confront him.
"I didn't think about it at the time," Evans said during the reunion of Jace's reaction.
"All I thought about was that he almost hurt my son. He almost knocked my son out, and that's what [expletive] me off."
She is parent to Jace with Andrew Lewis, 4-year-old son Kaiser with Nathan Griffith and to 20-month-old daughter Ensley with David Eason.
