weed I went through phases with my rage that basically synced up with my healing process.
Nobody ever told me it was okay to be angry at what was done to me. My anger was scorned and punished by both my dad (abuser) and mum (enabler). It wasn't until well after I left home and sought counselling for the first time that I was told it was okay to be angry.
If I expressed anger as a child I was punished (dad) or emotionally abandoned (mum). So anger felt incredibly frightening to me; I thought if I expressed it, I would literally die. It took a long time to switch my thinking to understanding that I had to allow that anger to find its expression.
I'm gonna say about a year, in my case, from when I started expressing anger without fear of punishment. My H, who was also a survivor, helped me through that a lot. Just him saying it was okay to be bloody furious about not just the abuse, but the covering up by my mum, went a huge way towards getting rid of it.
My DS is 20 now and I know he knows everything necessary about consent. He has his own anger problems, stemming from abuse by his birth mum and her partner, but he has worked very hard to manage those, and mostly succeeds.
It's been a slow process to stop suppressing my anger - not about the abuse, just every day stuff - because I was trained so effectively not to show it (or fear, or pain, or sadness, for that matter.) It's been in the last year or so that I feel I've really cast off the last chains of my childhood.
There's a book called Homecoming, by John Bradshaw which has some inner child visualisation exercises which I've found immensely helpful. You might like to take a look at it. Although I was assaulted hundreds of times as a child, and raped repeatedly within a relationship in my 20s, it's the childhood wounds that seem to linger longest, and sink the deepest roots into your soul. You can read some of the content on the Amazon page if you use the "Look inside" thingy.
