Unconfirmed bitcoin transaction for more than 5 days

[nanapee]

Hello
I deposited 0.042105059 BTC from my bitcoin account (1KDcKTBTLWnLUED6yMA4Huj5CfzgKfuvJF) to Livecoin.net account.
(1DaHJ3ewQ3XBDxTLFQ4U9E9C4z8w9uEvGW) about 5 days ago but it is still unconfirmed in blockcain.
The transaction has 0/3 confirmations in blockchain and still pending and i learnt it is because of the transaction fee. Someone advice me to double spend but I don''t how to go about it.

Please can some miner here help me confirm my transaction on the blockchain for a fee.
