Well it happens and can happen so quick that it's scary. I guess I would say remember that it's a game and that you'll always have a chance to play again. I know it's an old adage but "there's always next time". Did you find yourself pressing too hard? Just relax and it'll come along.

Thanks for all the advice guys. I went to the range last night and went through 3 buckets of balls, just drove the first bucket to release frustration. Once I started working I realised I was lifting my head to quick and not making very good contact.
I guess I'm just a perfectionist. I like everything to just work. I used to be our opening batter in the local cricket team and averaged 70 over 4 seasons. One season I averaged 65 and also made the most ducks out of anyone in a year so I know any sport has it's ups and downs. We just have to develop methods and mechanisms to come back from it.

Unless you are getting paid to play golf, don't take it too seriously. If you let it get to you, you will struggle. Remember that you broke 80, go out and play another round and just put the 104 in the past. next time you get out, think of the 79, not the 104.

unless I'm playing the next day, I sulk for a day and really beat myself up over it. Probably not the best or even right answer but it's what I do, can't help it. After I'm done it's like hitting the refresh button and it's back to the range to try and work on with whatever was not working for me at that time. If it's a total CF of a round then I'm in for a loooong range session.

You need to remind yourself that even the best players in the world have their ups and downs and 1 bad round or even a few bad rounds dont mean you have suddenly forgotten how to play golf.
Put it out of your mind, working on your shortgame/putting and move on.

I go out again the next day for another 18 but spend a half hour on the range first. Usually when that happens to me it's because im trying to be too cute and precise with every shot. sometime's i just need to shut up, commit and hit. consider it an 18 hole mulligan.

I go back to my short game and work on chipping and pitching, which I always feel comfortable with. I then start hitting 3/4 shots until I feel I'm hitting those solid and then work to full shots. Good luck!

I've been playing for 35+ years and there are always going to be great days, good days and bad days. I don't get too high on the great days, and I don't let the bad days drag me down. I'm just like a dog when it comes to golf.........every day is a new day.

If you look at scores on the PGA tour for almost any tournament you will see a pro or two that has shot the odd 82 or 85 or something when they are capable of shooting 65, that is pretty much equivalent to what you are talking about, a 20 shot swing. An amateur - even a good one- that is used to scoring in the low to mid 80s or occasionally breaking 80 is going to shoot 100 once in a while or they either aren't being honest or they aren't challenging themselves in any meaningful way by playing new courses or playing a different tee or a different club setup.

Man, That seems to happen more than anyone realizes. But some of my best rounds have always followed my worst. Stay positive and try and go 79-104-79. Also when a round for me seems to go from bad to worse. That is when I usually start thinking of the round as a good practice session. Hit extra shots, putt and chips a few extra times (If you have time and the course isn't crowded). Stuff like that.
