Help with ETH stuck on Polygon

Could someone help me figure out what to do with my ETH that is on the Polygon Network? I transferred it to that network months ago to buy an NFT, but backed out. I recently tried to bridge it to the ETH mainnet but the gas fees are too high and I don't have enough ETH on that account to pay it. So I attempted to deposit more ETH to pay for the gas fee but that costs ~$150 to even get it onto the network. I read a post that I should just leave the ETH on Polygon and either stake or invest it, but I can't even do that because the ETH is stuck in a pending transaction. Help.
