The feeling of having a healthy supply of self-worth is something I can only imagine might have been more readily available, natural and automatic if I was able to see that in myself as a child. As an adult survivor of childhood abuse, self-worth was not supplied in healthy doses while growing up.
Kindness begins with how we see ourselves. Much of this depends on how we were treated as children. Unfortunately, childhood abuse survivors often grow up as adults who a have hard time seeing themselves with kindness. We don't realize the subconscious voices telling us that we're unlovable, we don't deserve happiness, we're ugly or we're useless.
