LPT stuck in staking limbo

I tried to stake my LPT 2 days ago. My ETH balance was lower than the projected fee [which by the way seems SUPER high at $40-50 USD], so I lowered my gas price. However, now I don’t have my LPT staked, I can’t cancel the transaction, and the transaction is showing as failed in Etherscan. Does anyone know how I can pull my LPT out of this limbo to try again to stake?
