When is the right time to talk about abuse?

So Day 1
We walked from Poole to Worth Matravers
Legs aching and knackered so will be brief
Struck by us being here on this mission surrounded by holidaymakers and day trippers who are here to relax and have fun
We are having fun too but with this bigger purpose. Restless is about visibility - we are wearing our project t shirts and starting conversations about childhood abuse and domestic violence.
Here (as in life) those conversations are incredibly hard to start - as a survivor it is always hard to speak up - I do it all the time - probably everyday - but it never comes out of my mouth without a moment of thought, of hesitation. The taboo and stigma, the silencing, secrecy and shame, the coercion and actual real threats made by perpetrators are still very much something I have to consciously overcome .
Let’s face it the subject of abuse is still very much what I call “a downer at the dinner party”. Something we all know is happening but find it hard to engage with.
So the question with me today is - when is the right time to talk about abuse? And why do I as a survivor have to carry the burden of worry of spoiling the holiday/dinner party/day out?
