My sponsor told me in early sobriety, "It was none of my business what others thought of me." What he was saying is we have to keep our side of the street clean and when we do others can do us no harm. Forever I tried to be something I was not because I was not rich enough successful enough, whatever enough I thought I was somehow defective. When I became OK with who I was people being mean just no longer carried the weight it used too.
The world is full of angry people. Let them be angry just don't allow them to live rent free in your head
