There are a few problems here. First, your transaction spends from this unconfirmed transaction:
https://blockchain.info/tx/53adee2f59c7ba40b6162bc67106c640949fa10880640c31a1333aed636d3602 Your transaction will not confirm until this transaction that it spends from confirms as well. That transaction pays a fee rate of ~63 satoshis/byte. The current recommended fee is 140 satoshis/byte according to
http://bitcoinfees.21.co/.
The next problem is that your transaction is absolutely massive. It is 16960 bytes in size, ~75 times larger than the average transaction size. That means that nodes are less likely to relay this transaction and it also means that you will need to pay a very large fee. The fee rate of the transaction is only 50 satoshis/byte, which is also less than the recommended.
Because there are two transactions that depend on each other being the problem here, there is not much that you can do. You can either wait for them to confirm, or ask a miner to confirm them for you.
For asking a miner, you can use this tool:
