I couldn't find that much but I found the same question as yours and this is another person comment. :3 hopefully that help :D
A diet that can lower your stress looks like something with a lot of fruits and vegis. Making sure you get a least one hour of exercise a day. Plus drinking tons of water and a some juices. Foods I'd consider would be pineapples, strawberries, bananas, cucumbers, carrots, and etc.
My personal, tentative wild guess is: <em>apnea</em>
Depends how much was originally in your system and what you are doing to treat it
The answer is OCD (Obsessive Compulsive Disorder)
Hope this helped!
It would probably be okay if they have a really bad disease or a type of cancer just to let them know
