I am honestly and genuinely deeply sorry for your unimaginable loss and in the most of tragic of circumstances.
I too have lost a son and its a pain like no other. Its earth shattering and soul destroying and you understand the true meaning of heartbreak.
You are experiencing every parents worst nightmare right now.
I totally understand you wanting to make sure someone is publicly blamed for this and that everyone knows and understands what really happened and why. Our parent mode switches on and we want answers and we want justice. And in some ways its the only way that we can even start to process what has happened to us, and to them.
As for 'this is my life now', unfortunately yes it is. But in time, you will slowly come to accept this. You won't like it but you will get there and you will do that because you know its what they would want for you. And because you have others that love and need you. You will come out the other end of this but it will be painful. I won't lie.
I remember after my son died thinking that I would never ever be able to smile or laugh again or feel any kind of happiness in any way. That I was doomed to a life of misery and sadness. I couldn't see out of the black hole, there was no light. But slowly, and with time, the light started to appear again.
Your son will never ever be forgotten, he lives within you, but you will emerge from this. You will be changed forever. You will never again be the person you were when he was here. But you can survive it.
Please do access help and counselling to help you deal with your loss. I talked and cried and wailed to my counsellor in a way I never could to family. She helped me pick up the pieces of my shattered life. Along with a good support group full of other mothers who were in the same boat as me, who understood my immense pain, this saved me from myself.
Sending you love x
