Rebuilding trust in ourselves after abuse is not easy, because not only has the abuser likely engaged in a relentless campaign to undermine this, but people may also have been conditioned during childhood the same or similar ways and they may also have been beating themselves up over it, too. It's not uncommon for people to feel foolish, stupid and very angry at themselves for what they believe they've allowed to happen. It's important to remember that you can't know what you don't know, and learn to forgive yourself for what you did when you were afraid, just trying to survive or unaware of what was happening.
