In diagnosing EXACTLY what happened to me. I started shooting in the 80's(just been playing 3 years) and then fell apart. Irons were all over the place...I got to the place where I just wanted to quit.
That's where I am today. Got to the low 80's and about 2 months ago everything started falling apart. Thanks to Hurricane Ike I haven't hit a golf ball in almost 2 weeks. I'll be busy at work and at home for the next 2 weeks and I'm not sure when the courses around here will reopen. Maybe this month long vacation from golf will bring back a good swing...
