'Anxiety is the space between the "now" and the "then".' (Richard Abell)

According to Wikipédia, anxiety is a generalized mood state that occurs without an identifiable triggering stimulus. As such, it is distinguished from fear, which occurs in the presence of an external threat. Additionally, fear is related to the specific behaviors of escape and avoidance, whereas anxiety is the result of threats that are perceived to be uncontrollable or unavoidable. Is a normal reaction to stress. It may help a person to deal with a difficult situation.

I just found out that chronic nail biting is considered a sub-group of OCD (Obsessive Compulsive Disorder). One of the characteristics of this sub-group is that they become habit patterns, and needs treatment. The biting nails behavior, when it starts, can be associated with tension/stress, but once estabilished as a habit, they may not really be associated with tension anymore.

Isn't it odd? I would never thought that the simple fact of biting nails could be so serious.
