Good that it has been confirmed. This is what you may want to try out should you get sucked in this scenario in the future: you can try to send say $0.5 to the same wallet that is unconfirmed using a higher fee, you may want to use between $2-$3 to send the $0.5 from the same wallet to the previous receiver's wallet or you can do the same stated above transaction to even another wallet. I have noticed that the transaction does get confirmed some minutes or hours after the second transaction might have been confirmed. In the case your transaction fee is up to 0.0001btc, you can use the free accelerator offered by viabtc .com at 00.00hrs.
