This is he transaction which i have  done at 16 december and it is still pending 
what to do ?
Unfortunately you paid a very low fee 53.223 sat/B 

And the transaction may never get any confirmations a very little chance 

In this case the transaction will be cancelled after a period of time and return to original address.

The next time you create a transaction you need to look for current average fee which is now as an example 620 sat/B (Satoshi per byte).
