We all have mental health just as we all have physical health. In the same way that our bodies cooperate with our wishes more on some days than others, and can be vulnerable to injury and illness, so too do our minds.  

Discussing mental health is no longer seen as taboo in most places and nor should it be. Openness about mental health, including our struggles as well as our triumphs, is key to making it just as routine to seek help and support when we need it for our minds in the same way that we think nothing of having a physical injury attended to by professionals.
