Will I loose weight?? please help!!?

[Kendall]

OK so I am 15 years old and I'm 5'2" (short yeah I know). I currently weigh 128 lbs and I'm a medium framed kind of girl. Alright so I have been on countless diets (aktins, P. I. N. K. Method, Tap out XT etc.) And I just find myself getting either bored with it or I was practically starving my body. So I decided to FINALLY do it the good healthy way! So my new lifestyle (not a diet) consists of breakfast (2 scrambled eggs with a side of a handful of fruits or a piece of multi grain ), snack (a banana or apple) lunch (toasted multi grain sandwich with a fair handful of Spring Mix, 3 tomatoes, and 4 slices of fat free turkey), snack ( tablespoon of peanut butter or the rest of my apple) and dinner is either a salad with cantaloupe, tomatoes, corn, cucumbers, raspberries, with a bit of salad dressing or a piece of chicken w/ corn or steamed veggies and I only drink water then I do interval running for 30+ minutes or a workout DVD. Will I loose 15-18 lbs by June 4 (approx over 4 months)?
