Right medicine, therapy, self help skills, can completely abolish anxiety. This statement is a MYTH.
Aim of any intervention for treating anxiety, be it in form of self help, medications, expert advice of a psychiatrist or psychologist- is about learning to ‘manage’ anxiety and not really about curing it.
In situations where ‘anxiety’ is a psychological manifestation of an underlying physical condition like thyroid dysfunction, anaemia etc., it completely disappears on treatment of the underlying cause.
Attempts to completely abolish anxiety usually fail and thus, add to distress and despair.
Learning to cope with anxiety and building strategies to manage it is the key.
