OP, please take what I say not as a telling off or as sanctimonious preaching from my high horse, but some genuine advice meant in good faith.
You may or may not get a ticket, all you can do now is wait to find out. It will either arrive or it won't. Try not to stress because either way you won't end up in jail, 80 in a 60 is 3 points and a fine. If you were doing 81 or more it may end up in court. Either way this too shall pass, it won't last forever and you will be okay. It might be stressful or upsetting, but that feeling won't last forever, you WILL be okay.
I fully understand that now and again, creeping over the speed limits does happen and we are almost all guilty of it, but come on OP, 80 in a 60 is a fair whack over the limit. I'm all for driving as close to the speed limit as possible where safe to do so, so as not to hold up others on the road, but there's really no reason for going that fast as I'm sure you know.
Remember that if you had a crash going at 80, not only would it be more likely to hurt yourself and others, but if there were serious injuries or fatalities, there's the likelihood you could be charged with "death by dangerous driving" which carries a prison sentence, all for something you could have easily prevented.
You don't seem like a bad person, you weren't speeding maliciously, you weren't intending on being dangerous but the fact is, it is dangerous. You could be the safest driver in the world but if you're going 80 and someone else makes a mistake in front of you such as pulling out on you, you've got much less time to react to it.
I hope that this fright of the threat of a fine and points is enough to bring your speed down to the legal limits, not only will it be safer but you'll save yourself some fuel too, and you won't panic next time you pass a police car as you'll be in the knowledge that you weren't speeding. From now on, enjoy the weight off your shoulders knowing that you simply cannot get done for speeding, as you won't be speeding, and any speed camera or police car can just be forgotten about rather than feeling the worry that you are right now.
Best wishes OP, try not to worry too much. We all make mistakes, we are all human, but what's important is that you learn from it 🙂
