You can try free accelerators, however it already looks like its been confirmed.

The blockchain is heavily congested in recent times due to the selling and buying of BTC. The only thing you can do is pay more in fees, or pay to an accelerator. Thats about it.

I am just rooting for the lightning network to come and solve these transaction fee/time issues that are making Bitcoin look less and less appealing to be used as a currency for smaller transactions.
