Do do treat yourself as you should?

I often see clients very generous with others but hard upon themselves, they have been manipulated by, parents, teachers, who ever, to believe that they are worthless, so they have troubles with weight, health, money, self esteem, it's not easy to make a person understand that it's only manipulation, because it takes years to come into the state of feeling worthless so it takes some time to get out of it too, but it is possible, they need to realize how things really are, that they are WORTHY and do the daily work, in front of their mirror, looking at themselves with the same eyes that looks upon others with tolerance, looking at themselves with love and forgiveness, in doing so each day, they will eventually re program themselves and find happiness, how can we possibly love others if we are unable to love ourselves? But I know it is so, people don't love themselves as they should.
