Emotional Trauma
A number of times, inefficient management of trauma can produce lasting effects. Repeated emotional trauma without chance and time for recovery can cause mental health issues. A very convincing example in this regard is the basis of separation anxiety. Children who experience separation, divorced parents, or who fail to cope with the death of a dear pet, may develop separation anxiety associated with any other closed relationship.
Similarly, the emotional burden of workplace, consistent deadlines, reprimanding seniors, can all lead to the development of anxiety in already prone individuals.
