I thoroughly agree on writing as a healing too. Often I write my poems when I need to clear my head of the roundabout of thoughts and sharing my own stories on Steemit has been cathartic. I'm sorry you and your son had to go through that. I remember vividly in the UK, the Dunblane shooting, being told about it and how it made me feel. I was nowhere near it and had no family involved, so can only imagine how tough that was.
The craziest thing is the disbelief. You cannot wrap your head around it, I kept thinking this never really happens
To this day it is surreal. I do not know if it will ever feel like reality.
