A mental illness that involves excessive, exaggerated anxiety and worry about everyday life events. It differs from regular anxiety in the way that little worries are over analyzed to the point of a possible anxiety attack which is very similar to a panic attack.
Some symptoms are:
unrealistic view of problems
being easily startled
"I wasn't able to finish my paper because I saved it until the last minute and I had an anxiety attack because I have generalized anxiety disorder."
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.
