Nothing much you can do except to wait. A transaction of your size would have to pay a fee of 0.0008BTC to confirm and yours is much lower. I expect it to confirm in several hours and if it doesn't, PM me and I'll help you to remove the transaction from
the mempool your client. The process can take up to days so I would think your transaction would confirm before that.
