Looking at your numbers, you are a small person...correct? Why are you focusing on scale weight? Toss out your scale, and use a tape measure and a the mirror!! You can lose inches, gain lean body mass, lose body fat without the scale moving one pound.
Lift weights, do some cardio, eat a healthy diet - dump processed food, including diet drinks. Spend time looking for healthy recipes to keep your diet tasty and healty. Trust me, I know from experience...the worst thing you can do is push your body into losing scale weight. You want to give your body a nudge, not a hard push to let go of body fat.
If you use the scale and focus on a magic number, you will never be happy with your body comp, and will find yourself on a perpetual low calorie diet.
Shift your thinking away from quick scale results, and give yourself 6 months to a year to recomp your body. Adopt healthy eating habits that will last a lifetime. Trust me, you don't want to adopt a diet mentality, it's a vicious cycle that can lead to metabolic damage. It's not as simple as calories in vs calories out. Take care of your one and only body, and focus on fueling with nutrient dense food.
