Anxiety has a purpose. Originally the purpose was to protect the existence of the caveman from wild beasts and savage neighbors. Nowadays the ocassions for anxiety are very different - we are afraid of losing out in the competition, feeling unwanted, isolated, and ostracized. But the purpose of anxiety is still to protect us from dangers that threaten the same things: our existence or values that we identify with our existence. This normal anxiety of life cannot be avoided except at the price of apathy or the numbing of one's sensibilities and imagination.
