Which would be the best ways to heal childhood trauma?
To a certain extent, ridding oneself of the notion of 'healing'. In much the same way as getting over the loss of a loved one, I think the terminology is misleading.
I would suggest taking healthy steps (counselling etc) that can help us better understand what has happened and to integrate it as part of the whole that we are.
However I will say that I've never suffered childhood trauma, so I'm speaking from opinion rather than experience. But it's the understanding that we may never heal, in the same way as the body form scars that we may or may not learn to live with the appearance of physical scars - or the scarification of the mind once a wound has been inflicted.
I think this may help rid oneself of the notion that because my mind is scarred in this way from chilldhood trauma, I'm somehow less than what I ought to be. But this denies that person the incredible social good they may be able to contribute through the sharing of their story and through the empathy they may develop for others who had suffered similarly.
Of course that individual who is a victim of childhood trauma owes nothing like sharing their story unless they so wish.
Acknowledge your trauma and get a help you need.
Stay away from toxic people.
Eat healthy and take care of your self.
It can't hurt you anymore.
Have lazy days.
Spend time with your favourite people.
In the end, it comes to your willing power to overcome it.
These techniques will help you decrease the intensity of trauma but they won't make you forget your trauma and bad memories.
