Don't try so hard. You loose motivation, not weight :)
First step: You should look at your normal, everyday diet.
Second step: think about a number of calories, the ratio of fat and protein to carbon, your habits like how many meals you have per day etc.
The third step (the hardest): take your conclusions and try to enhance your habits. For example, if you eat too much, try to finish a meal when you're not full and eat minimum 15-20 minutes; if you eat too many fats, try to cook more than firing plus eat a lot of fruits and vegetables; try to have 5 meals every 2-3 hours - eat less but more frequently. This part should take 3-6 weeks when you calculate every calory. The best time to list it is when you prepare to the dish - it is easier to prepare less than eating less.
Fourth step: when you have healthy habits you should (!!! yes, I mean it) stop tracking calories. Before you lost motivation. Sure from time to time, you can list calories, fats etc. per day or two, to check that your habits are still healthy.
