WotLK Character disappeared

[Mage69]

Hello, so i downloaded the game again after a year and i see that my character is gone. I checked every realm and checked in the services tab also.

Character level, and realm?

If Frostmourne, you probably played during S1. So you'd need to go to services and select Frostmourne S1 and transfer your character to Icecrown.
Any other realm, I would guess somebody had access to your account, and sold your character and sent the coins to themselves, or cleaned and deleted your character.
You may also want to check if they are in Barracks for some odd reason. https://www.warmane.com/account/barracks
