Used the wrong network

I made a rookie error when moving my coins to a hardware wallet and looking for a definitive answer if they are fully lost or not. I finally got myself a hardware wallet and contracted dengue fever this week but rather then wait until I was better I went ahead and started using my new wallet and sent my polygon matic (not erc20) to my eth wallet’s address. Because it’s still my eth address is there a way to reverse this? I was reading something online and it was saying about using your keys to create another wallet to get at then that way but I dunno I’m super lost, it wasn’t many coins because I remembered to send test money first so not a big deal but just don’t know if it’s fully lost or not.
