Kerogima

Hello, I disconnected late this night (around 3 AM) in Orgrimmar with around 45 gold on my mage named Aisslanz. When I reconnected today I was in Kargath where my HS is and I had only 16 silver left but all my items are still here. I don't know if it's a bug or if my account has been hacked because I still have my stuff. Is there a solution or would I have to farm again from the begining?
