I eat 200-950 calories. I'm OBSESSED with my body and my weight. I'm 5'3 and I weight 87 pounds.

Answer:
You’re very short so your proper weight shouldn't be very high. But in no way should you overly obsess about your body. 200 calories isn’t acceptable for anyone. Its very destructive to eat that tiny. Your body will consume whatever it can and when there’s no food it will eat away muscle.
Be happy with yourself first and foremost!! It sounds to me like you may want to seek assistance. A brief session with a psychiatrist could be very helpful and there are many tips to help you be more satisfied with who you really are, not who you obsess over. Good luck.
Answer:
There's a big difference between you and the person who is 4'11″. You’re 20 lbs under the low end of the weight chart for your weight and they’re 2 lbs below it. The fact that you are so underweight and that you think you might have an issue is enough to see a physician.

Its hard to be a mainstream female in the country and NOT be obsessed with your weight so that’s not an indicator but the fact that you're so underweight seems to be a red flag my friend.

I hope you seek professional help immediately. Anorexia if left untreated can be deadly.

Answer:
Based on the details you gave, you sound like you could be anorexic. Someone of your height should weigh between 111-125 lbs. you shouldn't obsess about your weight, its not worth it. Starving yourself with so few calories that you do eat could do serious damage to your organs. Don't listen to Hollywood in what they tell you about “being skinny is beautiful.”
Answer:
Yes. You’re very underweight. You should weigh at least 20 pounds more to be even at the low end of healthy weight for your height. 200-950 isn’t almost enough calories. You need at least 1200-1500. You are starving yourself. You need professional help. A more healthy way to manage your weight is proper nutrition and exercise.
