International health insurance policyholders may be among those who are coming forward to discuss and seek support for their depression.
According to Emer O'Neill, chief executive of the Depression Alliance, the stigma surrounding the mental health condition is starting to lift, while more people are realising there is a difference between a "sort of general sadness and clinical depression".
However, sufferers themselves often associate negative emotions with the condition.
"People do often feel that they just can't separate out the emotions that are going on and the support that you need really. There is of course almost a guilt that often comes with depression – that guilt and restlessness that you are not strong enough and you should be able to get through this on your own," she pointed out.
Ms O'Neill's comments come after actress Gwyneth Paltrow spoke out about her postnatal depression, saying the hardest part for her was admitting there was a problem.
