Weight loss obsession? Or is this normal?

Here is the deal. A lot of people I know say that I don't need to lose any weight, but I am in my skin and I see something different. I am 5'10 and 140 lbs (yay me! I lost 2.5 lbs in the past week and a half). I've been cutting back on simple carbs big time, eating lean meats and eating more vegetables. I was so hungry when I first began trying to lose weight about a month and a half ago, but now I notice, I don't even crave food anymore. I take no supplements or aides to lose weight, just vitamins and trace minerals in my water/cooking. Now it's easy for me to stick to 800-1,000 calories per day and I am aiming for less. I eat things like, kidney beans and tomato paste stew, chicken breast with spinach, and I'll have fruit days and vegetable days (just what it sounds like). I don't do rice or bread anymore and NO junkfood or soda. I want to get to 134 lbs. by June. Is this obsession, or just a normal weight loss goal?
