A chemical brain disorder that causes one to worry about everything, even things they don't particularly care about. Also causes one to not be able to relax properly. Most people do not take this disorder seriously, even though it is very serious and can cause a lot of problems in a sufferer's life.

headaches
sweating
trembling
difficultly concentrating
being easily startled
insomnia

AKA: GAD
