Someone Got Into my Metamask / Lido Staking Account and Stole 18.25 Eth – Is there anything I can do?

Hello all,

Currently fighting back a panic attack – I just logged into my Metamask for the first time in awhile today because apparently some NFT I was selling on Opensea finally sold (legit forgot I posted it). I logged in – all my Eth – staked or otherwise – is all gone (except what I got from this sale, apparently). Here is my etherscan: https://etherscan.io/address/0x0c0771096c209517536d53b20b868fb974626174

I am fearful of the answer but I have to ask anyway – is there ANYTHING I can do to recover this? I have been slowly building this bag since 2017, this is absolutely devastating. I’m not sure how anyone could have gotten the necessary keys, they are not on my computer anywhere.

Is there anything I can do? Or am I now just out $40k?

Tracked my eth to this account: https://etherscan.io/address/0x97dc5b190fb6e8a793803191356aaf6475adf0a7
