The thing that worked for me was accepting the child(ren) I was at various ages, loving them, reassuring them. I did it accidentally for myself, through seeing some childhood photos for the first time & wanting to comfort that child; then I found out this was a recommended therapeutic technique!
Yes, as you approach memories which have been locked away for a long time, there will be fear & resistance. A good therapist will help you deal with that so you can discover what's inside yourself, without pushing or implanting anything from the outside. It's the children's story to tell, because they lived it & they know - & they've kept it & you safe for years. Honour that. Never try to push them. Allow them to feel safe enough in the here & now (tell them that things are different, explain to them what's changed, how your life has gone, who from the past is dead now, etc), & when they feel safe enough they'll tell you what happened & how they felt about it. It's not easy work, but it's worth doing if you have the time & space & professional support & can do it safely.
It's not always a smooth road, either, but overall the movement is towards healing & a greater wholeness. So if there are setbacks, don't give up or think the battle is lost. I'm saying that because in the beginning I thought everything would be progress, & when I ran into difficulties I was taken aback. I also thought it would take me a couple of years to be 'perfect'. Neither part of that was correct!
I think the core of this stuff is that we all need certain things in our childhood in order to grow easily, happily & healthily - the same way a plant needs certain things like sunlight & water to grow to be the best it can & reach its full potential. Anything that stops this (bereavement, family breakdown, bullying etc) is reason enough. It doesn't have to be sexual abuse.
Good luck to everyone who's concerned about this.
