What a terrible tennis season

The summer tennis season ended this past week. I broke strings on two of my rackets and I figure that sort of sums up my season this summer so far. All of my matches were pretty close, but I couldn't pull any of them out. I finished 2-5 for the summer session and frustrated is the mildest term I would use. 

I can't quite say exactly what it is that has me not playing well. In fact I feel I am mostly playing good tennis, but it seems like I am either hitting winners or hitting unforced errors into the net. Perhaps it is a patience thing. Let's just hope the fall season plays a bit better.
