You are young and only 105 lbs.
Are you sure you need to lose it? Why not exercise a little more and get fitter if you are concerned about your image? Exercise makes you feel good, stronger and healthier. It is not healthy to lose 5 lbs. a week safely, especially given that that (10 lbs. that you want to lose) is 10% of your current weight.
Why not just eat healthier whole foods. Good choices of good foods will fill you and automatically have you reducing calories on junk food. Cut out whites, salt, sugar, white rice and white bread. Easy peasy, and presto!
I think you should concentrate more on your overall health rather than weight alone.
