Why do I sometimes feel so sad?  

I now understand personally, as someone who has suffered unbalanced emotions throughout life, that some people believe that depression is something that is unnatural and it must be 'healed'.   

My experience is that depression and anxiety come from imbalances within our energy subtle bodies; a delayed response to anything that impacts on our harmony or, inner joy.   

When I choose to allow my emotions to be what they are, I can also choose the path of healing that is right for me.   

Healing does not happen in a linear fashion. It causes for us to pay attention, allow and mostly forgive ourselves for believing (whatever that is that has made us believe) that we are wrong, not right, not acceptable and above all, not lovable.
