Don't feel too down, Katie. At the end of my first year I was having great problems (more with my postdoc rather than supervisor). I felt i didn't have any results and felt like jacking it all in. But stick with and things will come good. If it is a science PhD you are doing you will find reults hard to come by in the first year and even most of the second year, but they will come and you will feel great when they do. Good luck.
