Rocker PETE WENTZ has exposed his troubled mind after revealing he suffers from attention deficit disorder, depression, anxiety, insomnia and has to have treatment for anger management.

In a recent interview Pete inadvertently revealed himself to be the celeb we would least like to be stuck in a lift with, after confessing he has to take a whole host of prescription drugs to keep his illnesses under control.

The Fall Out Boy star, who is expecting his first child with new wife ASHLEE SIMPSON, says he has to carefully balance the sleeping pills he takes to nod off at night - because a wrong dosage keeps him awake hallucinating.

Pete says that without sleeping medication he can only sleep for an hour at a time.

Wentz explains, "If I don't take an Ambien, I'll sleep for an hour. With Ambien, I'll sleep from 2am to seven (am). But, if you don't fall asleep, Ambien makes you hallucinate.

"About four months ago I took Ambien and almost set the house on fire."

And the fact that wife Ashlee is pregnant only serves to make matters worse: "She goes to bed at eight... so it's just me and the dogs, hanging out. You don't even know the transcendent conversations we have."

Okaaaaaaay....
