Trust Wallet View-Only Wallet

Hi there, Someone guided me online to set up my trust wallet by the promise of helping me recover my stolen cryptos on another platform. I never shared my passcodes or seed phrases but the end result was a view-only wallet attached to a smart contract on the blockchain! I read online that I needed to revoke my access to be able to use my funds again but the person tells me that I would lose all my funds by doing so. I also noticed that $304 from my main wallet got disappeared without me having taken any action! Would you please assist me to resolve these issues? I do appreciate your help
