Calorie Boredom

I am afraid that I have become a calorie counter... In an attempt to put on weight I'm counting calories in order to eat at least 2500 calories a day. Recently, my weight has plateau-ed and I could really do with putting on another stone. I am keeping a food diary to make sure I eat enough every day, but now it's starting to dominate my conversations. I know at any given point in a day just how many calories I've eaten and which foods are the higher calorie options on the menu. Food is no longer fun, it's fuel. I can't enjoy something unless I know how much it's contributing to my daily target. I get panicky when I reach dinner-time and I'm not at least half-way through my quota. I love food, this is not right, I want to rediscover the enjoyment. I know it's not forever, but it's already boring me. 1175 calories so far...
