It will get confirmed at some point for sure. There are currently 25k+ unconfirmed transactions, which is quite much because around 1500-3000 transactions fit on a block depending on their size.
There are few people offering transaction acceleration service. However i recommend tipping at some point because they are using their time for doing this service to the forum members.
Posting into one of these threads should get your transaction confirmed within 2-8 blocks or so on:

CoolWave's accelerator service
natiak482's accelerator service
Thekool1s's accelerator service

I hope that you get your transaction confirmed from one of these services
