As you don't have any other balance left on your mew wallet, I will suggest you to cancel the transaction. MEW have the feature on it. You can either speed up a transaction with adding extra gas fee or you can cancel the transaction also. Please check out this article and follow the steps to cancel the transaction and then resend it with more gas fee. As you save 125 ETH it will not be a problem to spend some extra gas to save your time.
