The core of childhood issues is the mandate that present-day conditions be--in any way possible--maintained the way they were in childhood. So, if you lived in fear and anxiety, in your life today you are constantly--without being aware of it--taking physical actions to maintain the atmosphere of fear and anxiety.
From giving psychic readings, I see that this problem can be approached from another direction by starting to imagine a life of safety, security, peace and protection--a life that is comfortable.
You actually have to get used to having a great life. And the way to do it is to first start thinking about, then maybe writing about, then perhaps visualizing this sort of life in a self-guided meditation. You take steps. But the objective always is to accept a life of peace, prosperity, safety and comfort.
