fears and phobias
Most phobias can be easily cured using various techniques to help learn new behaviour patterns i.e. a calm reaction rather than a panic reaction.
Sometimes, if a phobia is deeper and more disruptive, then it may be necessary to look at some of the issues surrounding the onset of the phobia, and work to resolve them.
Phobias are often rooted in childhood misunderstanding.
For example, a child doesn't necessarily have the logical tools and information to understand the meaning of a parent standing on a stool screaming at a small insect. They will almost certainly make a deep unconscious decision that the insect is dangerous.
