I know why you got yourself your steemit name:) I deal a lot with psychology and think about causes & conditions.

I wouldn't add anything of what you've described. How hate feels and how I observe when I myself am having feelings of hate, is quite frightening. In the end it is the lack of self love and not trusting in self and others. Most things which I did hate in the past seemed ridiculous in retrospective.

"It'll all go away", that sentence helped me a lot when my hair started to burn because my brain was on fire. Of course, everything passes, the good & the bad. Love, hate, trust, fear, joy, taste, smell, ....

But one doesn't have to understand that wrong. It of course matters what the moment delivers and to have strong ethics.
