Oddly enough, I am going through some very similar experiences myself. I agree with what PBA and GetOffMe10Pin said. I am having trouble understand what the lanes are telling me, and I'm letting it kill me both upstairs and on my physical game. So today I took it one throw at a time.
So today during league, after 4 or 5 sets where I struggled hard and bowled pretty bad, I focused on each shot by itself. Throw the ball, make sure I don't just go through the motions but take each shot one at a time and don't fall into any more bad habits. Make a good shot, don't rush my feet, and my problem has been grabbing lately. So I focused on all that and it all came together for me in a great third game. But it was the most comfy I felt bowling in ages. I took one frame at a time, and made sure it was quality. I had some great strikes (crazy sloppy carry lol), and made all my single pin spares. Two things I haven't done in a month.
Hope you get out of the funk soon!
