Teenagers
Acne - Anxiety - Depression - Puberty - Hormones - Sleep Disturbances 

Teenagers are moody, erratic,  impulsive and often get frustrated with situations and themselves, this is due to an underdeveloped frontal lobe, which doesn't mature until the age of 25. Many parents see their behaviour as just being difficult and often conflict will arise due to the frustration of everyday situations.  This is a time when anxiety and mental illness can arise. 
​ Lets not forget the hormonal changes, puberty, physiological changes and the social pressure to succeed and do well in school.
