When one or more chronic health conditions or a disability enter your biography, much of your previous abilities, social life, professional life and once-future expectations come to a sudden end. The grief soon after these realisations can, over time, develop into a chronic sadness.

Whereas grieving is necessary in a process of endings/death/separation, when it continues past its beneficial function, it can prevent you from making a new beginning and claiming back your power.
