This question already has an answer here:
I have an issue that's probably happened lots of people already, so I'm really sorry for asking the same question. My transaction is stuck since 28.12.2017 already. I've accidentally paid not enough fee to ever get it confirmed. I wanted to pay 0.0001BTC but I've paid a total fee of 0.00001BTC. So not even a transaction accelerator can help me out with this problem anymore. My question is now, what can I do to get my bitcoins back or even get it ever confiormed?
