I'm going to go along with what the others have said thus far and add a bit to it.
I think it is up to each of us to decide if trudging through past memories is going to be useful to us or not. As Hogan says, you can re-traumatize yourself by going back there and running through those things.
As I proceed through the healing process, I am finding things that need to come up. They're coming up whether I want them to or not and its because I have to work through them.
If I can for a moment borrow some thoughts from fellow board user arronb and relate this to chronic pain.
arronb recently told me that "the brain can only handle one kind of pain at a time"
which is so true. He went on to say that Someone who has a chronically sore arm or back will likely forget about the pain if they were to break their leg. However, once their leg is healed, the pain from the chronically sore arm or back will re-enter their mind.
That being said, as we uncover and heal emotional pain, we will become aware of new pain that isn't actually 'new' pain -- it's been there the whole time, but now we're ready to deal with it and therefore it has entered into our consciousness.
Also I should be careful to say that it's not just pain we're dealing with. Yes pain is underlying pretty much all that other stuff we're going through but topics such as shame and fear are every bit as important to recognize and work through.
As children, we didn't know what to do about all this 'stuff' so we just buried it and saved it for later. While it may seem hopeless at times as though the pit is never ending... Have a look at recent posts by users endlessjourney and kellygtx... They are now living proof that we do get to the bottom of it eventually and once we heal from those final things, it'll be time to start filling that empty cavern with happy healthy things from which we can draw strength from.
So, I don't think we need to trudge through every single thing thats back there... But there is a certain amount of 'stuff' that our mind and heart absolutely need to have a look at and heal from. Other things that we buried long ago maybe won't look so bad now from adult eyes and we will release those things easily.
For me it has been incredibly helpful for me to get 'in touch' with the little guy inside as... quite simply... I deal with alot of self-blame issues and its very helpful to see how innocent he was waaaaaay back in the day when it started.
I dunno, hope all this has gone to help you with what you're chewing on. Just some thoughts I had as I read thru your post
All the best,
