This is a recording of a short talk I recently, I discuss what causes anxiety.  gave Anxiety disorders are said to be one of the most common forms of mental illness in the world and mental illness is said to be the most common form of illness, in the UK it is estimated that 25% of the population suffers with anxiety or depression and 9% suffers with both anxiety and depression but anxiety is actually a natural response to danger it is not a disease and it’s not a disorder or a mental illness.
