The singer and rapper admitted that he took on too much at once by releasing his directional debut iLL Manors and album of the same name simultaneously.
He told Daily Star: "I was offered everything I'd ever wanted at exactly the same time.
"I thought I'd be able to do it all to a high standard, and have a personal life, and obviously that wasn't realistic."
Discussing his upcoming holiday, the star insisted: "I'm going to have to be very careful about what to do next. I'm going to have a break and think about that."
Plan B - whose real name is Ben Drew - also stars in the upcoming film The Sweeney alongside Ray Winstone.
His iLL Manors album topped the charts in July this year and re-entered the top ten on last Sunday's Official Chart.
