Still shaking my head

Wow the downswing continues. My yearly ROI has plummetted from 86% on April 13th to 24% now over around 300 tourneys. Meh - so much for volume being the answer. The crazy thing is I feel so good about my game but am starting to doubt myself even though I really can't find many mistakes when I review my HHs. I feel like I am starting to press when I get a stack - but then when I back off and tell myself to be patient I never win the races I need. I am going to put a full session in tomorrow and then I might play on like Wednesday next week, but other than that I will not be playing again until Vegas just to take a mental break from the game and to get the house in order before I leave.
