I often come across the phrase that people "use this or that as a crutch". Recently I have seen quite a few people referring to using the diagnosis of ADD as a crutch. When this is has been said it has a negative connotation towards it. It almost as if these people are saying that people are using the diagnosis or label of Attention Deficit Disorder as an excuse. An excuse is not the same thing as a crutch.
A crutch is something that helps support a person. A person uses a pair of crutches to help him or her walk when there is something preventing him or her from walking correctly. Maybe people are in fact using the Attention Deficit Disorder as a crutch. For many people being diagnosed with Attention Deficit Disorder does support them. They finally have a reason for why their brains work they way the do and from there can learn better ways manage their lives.
So maybe if people are actually using the term crutch correctly then the label of ADD is a crutch.
