Nightly reflection...

Over the course of the last few nights, while doing my daily reflecting (on a suggestion of my sponsor), I've had a hard time accepting, I guess you could say, that I haven't really fallen short during the day. What my mind always goes to is my day at work (I work in retail, so I am constantly in a position where I'm dealing with people the majority of the work-day). Like I said, I'm not seeing many, if any, faults in my daily actions or thoughts. Being just over a month sober, having done my 4th, 5th, 6th, and 7th step, I keep having the thought while reflecting on my day that I should be fucking up more than I am, or not really remembering much of my day at all. This gets me confused and then frustrated, so much so that I have a hard time finishing my routein. I've been praying every morning, and trying to meditate all through out the day (because of some non-AA spiritual reading I've been doing), but like I said I'm confused as hell. Is there something that I'm doing wrong? Help please... BTW, I tried calling my sponsor, like I told him I was going to, and got no answer or reply. I'm seeking help because this has been weighing heavy on my mind the last few nights.
