Here’s a quote worth thinking about from Stop Being Mean to Yourself: A Story About Finding The True Meaning of Self-Love:
There are many drugs that can injure the body and deaden the soul — cocaine, alcohol, heroin, marijuana. But there are other drugs whose narcotic power we overlook. Disillusionment and betrayal can grind away at our souls until all our faith and hope are gone. The cumulative effect of a lifetime of disappointments can leave us confused, lost, and dulled. Whether it happens in one moment or over many years, losing faith deadens the spirit like a syringe filled with heroin or a line of coke. The most debilitating drug on this planet besides losing faith in God is when we stop believing in ourselves.
