I agree with the last comment, it is about moving on - in the beginning he is mad with jealousy of his lost love's new boyfriend and he doesn't believe that he knows her as well as he used to. As he realizes that he can never win her back, he becomes suicidal and travels across the country with her ghost (= the memory of her), re-experiencing memories on the way. The use of "drug" instead of "dragged" could mean that he uses drugs and then her ghost grows stronger ("WE plotted out my death", i.e. drug addict Conor and the ghost). Then he has second thoughts and digs his teeth into his knees (yes, I think that's litterally) and calls the lost love. Later on he tries to forget the girl by being with another girl, an abused girl ("a broken jaw that her father gave to her"). I have no idea about the meaning of the tomato thing, but since the secret concealed in the tomato field (which could be something that happened there, it doesn't have to be a buried thing) only stretched to the diary entry's end - maybe Conor reveals it in this entry?
Someone said the "calendar" and "clock" are in fact people killing themselves. Don't think so. I think the meaning of that verse is just that the time (i.e. calendar/clock) when he was with her is slipping further and further away (= dying, the calendar of that time is hanging itself). But in the end he decides that he can't be trapped in the past ("But I will not weep for those dying days") and he realizes there are other people in the world than that girl, and they help him to recover from his heartache. So, as much as it is a song about missing someone, it is a song about moving on and appreciating what you have left.
