If you can, better switch to much more stable wallet like electrum as you have more options when problems arises. Anyways, I quequed your transaction on Antpool and confirmtx although i never accelerated a transaction with no fee. If it doesn't confirm within 12 hours then you'll just have to wait for the network to drop your transaction and thus the coins will be returned to you.
