You should not be losing weight ! Especially at the weight your at, it could become very dangerous for your health !

I don't think you need to lose weight you need professional help as you appear to have and eating disorder

exercise, drink plenty of water befor u eat...

watch what you eat, eat fruits and vegtables, eliminate fried foods try baked, eliminate some meats eat more fruits and vegtables and exercise/jogging or treadmil is great
good luck

I don't think you need to loose weight you are probably underweight and if anything you need to gain weight.

Please don't try to lose any more weight, you are extremely underweight as it is. You might want to see a doctor, though. You could have an eating disorder, at least that's what it sounds like.
