I hated the world too in early sobriety. I had a lot of underlying emotional issues that I had been numbing with alcohol. When there was no comfortably numb juice in my system, the anger presented itself.
I would strongly suggest a program, any kind of program, AA or a secular program. many of the secular programs use the 12 step method which is a self-improvement program that helps us understand our underlying issues, our view of ourselves and our relationship to the world.
