In my honest opinion, most people who strut around claiming that "love solves everybody's problems" or "love yourself to love others" like it's so easy are little more than self righteous pompous individuals who have never had to suffer or struggle in their lives.

Fact of the matter is that many of the most damaged people are some of the kindest and most loving people one could ever meet because they know what it's like to truly suffer, therefore, they learn to truly cherish and appreciate those closest to them in such a matter that a normal person would be incapable of and as a result, they usually go out of their way to make those they cherish the most happy so that their loved ones don't suffer as they suffer.
