Demi Lovato jokes about Disney Channel Post Traumatic Stress Disorder

Pop star Demi Lovato has joked about suffering from Post Traumatic Stress Disorder (PTSD) from her Disney Channel days.

The 23-year-old rose to fame in the network's TV movie Camp Rock and Camp Rock 2: The Final Jam, starring alongside the Jonas Brothers, but having such a hectic work schedule at such a young age has left its mark on Demi.

"We joked around that it was Disney High, except we all were shooting shows and really overworking," she recalled to Billboard. "I joke that I sometimes have PTSD after leaving the channel, because if my schedule starts to get too busy, I rebel and I get b**chy."

Demi insists her own family never pressured her to work so hard, but she does feel that in the industry in general, there is a mentality as a child actor to work like someone much older.

"When you're on set, you work like an adult," she said. "I always wanted to be the next Shirley Temple, to be the youngest person to ever win a Grammy and an Oscar. It didn't turn out that way. I don't regret it, but I probably won't allow my kids to get into the industry unless it's on their terms."

Demi has certainly had her struggles since stepping into the limelight, entering rehab for drink and drug addiction, while also battling an eating disorder and self-harming issues.

Now clean and sober, the star recently revealed to American Way magazine she didn't see herself making it into her 20s at the height of her problems.

"I lived fast and I was going to die young," she said. "I didn't think I would make it to 21."
