Re-parent your inner child.
This makes so much sense, yet I've never thought of approaching it that way. It's so hard to undo what shaped your developing mind in childhood, even for someone raised in a fairly stable environment. Some never can undo that part and go on to continue the cycle or end up in a dark place.
The first step is admitting that it is there and still has a deep affect on you.
I am really serious here, so many people i have worked with have no idea that their child within is controlling their life. No one knows, so they do not know that needs to be healed.
One really weird thing is, if you go in with your inner-child, and change some of your past so that your inner-child had a good upbringing, many people will remember your new past.
