I lost my account

GM I gave my account to other people to play, but then I can"t log in to my account
Anymore. When I create my account long time ago I used random email so I can't do nothing to get my account instead of looking you for help. I know my user name. I needed help since I fell in to this game once again I want to take back the gun that I brought with zp. I appreciate your help, thank you.
