I can only speak from my own recent experience, which sounds identical to yours. I posted a few weeks back how I was feeling like I'd played well but wasn't posting a score. I carried on going and just tried to enjoy it but also spent a fair bit of time practicing - especially on the short game. I'd had round after round of enjoyable golf, but couldn't quite pull things together. Went out today and shot 4 under h/c. Nothing felt noticeably different, there were just far fewer silly mistakes.
I'd suggest replaying a round in your head to identify where you lost shots. Wild off the tee or collecting 3 putts like they're going out of fashion? I had a lot of advice given to me by fellow forumers about the short game being key and today was proof to me of how much of a difference that can make to a score. Be patient, put the practice time in if you can, and just try and enjoy it. It should come back!
Don't forget, the time you just missed the fairway, but you actually hit the fairway, it then hit a hump and went into the rough and then into a 6 inch hole in the rough
I'm going through the same right now. Woods and irons going straighter than they have for about 2 years after a lot of practice. Getting into scoring positions now but the putts just are not dropping - and they used to!
I think it's because there is pressure on that part of my game now that the other areas are coming together. It's like squeezing a balloon - the errors just pop up somewhere else!!
Driving well but irons are erratic and chipping/putting is saving me a score each time and somehow again at the weekend saved myself going back up 0.1.
Hanging by a thread though and will surely snap soon!!
