1k HD - getting hacked off

Getting truly hacked off with this now - there where a few "distractions" in the work gym eg PM4 decided to reset itself, class of about 12 people being shown around (but luckily that was only during the warm up) then when I came to the row there was one guy knocking around for the actual row and I was just not able to concntrate and my mind drifted then the pace did and I am feckin fuming at my own mental weakness - why can't I nail this - WTF is wrong with my head - it's not even 3 feckin minutes!
