Ok, I am 18 years old and am 6'4". I weigh 215 pounds. I have little muscle so the weight is mostly fat. 3 days a week, I run high-intensity intervals for 15 minutes. The other 3 days are lifting (days of chest (bench press), legs (squats), arms/shoulders (dumbbell stuff), and one day of rest. I have also cut back my calories to around ~1900 per day when I was getting around 3000 before. And the calories I eat now are healthier (oatmeal in the morning, chicken breasts, veggies, etc) with small amounts of junk food whereas before it was all junk food. I don't understand what's wrong?
