Wallet drained after signing what seemed like a routine Metamask transaction – is there any hope?

hi everyone, feeling pretty low right now. i usually consider myself pretty careful but i think i messed up big time. i was trying to claim some airdrop for a new token i'd heard about, something pretty small, maybe 100 bucks worth. the website looked fine, i connected my MetaMask wallet, and then it asked me to sign a transaction. it looked like a normal sign request, not a huge gas fee or anything. i didn't think much of it, just clicked approve. next thing i know, like 10 minutes later, my entire wallet is GONE. all my ETH, my USDC, even the little bit of MATIC i had for gas. it was about 8.5k EUR in total. i checked Etherscan and saw a bunch of 'approve' transactions and then transfers to an address i don't recognize. i feel like such an idiot. i've heard about wallet drainers but always thought it wouldn't happen to me. is there *any* way to reverse this? or track it? i'm in Montpellier, my bank (Crédit Agricole) said they can't do anything because it's crypto. any advice is appreciated.
