I was one. I had a park service job and was a real prick. I lost it. I got back with God, a bit and decided to really care about others. I try. It is not easy. I want to help you if you are hurting though.
The ex was an arrogant bad tempered bully. My brother was an arrogant intellectual who made you feel inferior just using his Harvard accent. My brother turned out to be a nice person later on...for the same reason as you did.
