1 in 2 children will develop a mood or behavioural disorder or substance addiction by age 18. Sadly, boys & men are far less likely to seek help for a mental health condition than girls and women. Fear of looking "weak" or "unmanly" causes many guys to bottle up their feelings, with potentially disastrous results. Intervening when your son exhibits symptoms of anxiety or depression can change the trajectory of his life, for the better.
