Honestly man, I changed to Abnegation a long time ago when I was going through a lot of self-depreciation issues. Not to get into it too much but, it's always nagged at me that I couldn't change it to something more suited since I've since moved passed those days where I didn't really know who I was. I know it's dumb to most people to put meaning to a username, but I have always done in since I first changed my name to Abnegation. It's a long story, but I do have my reasons, it's not just change for the sake of such!
