Lost all my Etherium

Hi, I just tried to connect to Pancakeswap in my Metamask app browser to buy some FEG.

Then as I was trying exchange the $600 from Etherium to FEG it just all disappeared… Before i even really started the process. Now theres a $0 Balance…

Does anyone know what happened? Did I just get hacked somehow?

Cheers!

Sorry guys newbie here, I just changed networks at top and it appeared. :confused:
