Hi Christine!
Welcome!
From your post I notice that you mention diet but not exercise. My son is
6'4" and dropped 75 pounds by adding running to his daily routine. From your pictures I notice that you are quite slender from your waist up. Walking can trim a bottom half very well, too. My thunder thighs and big butt really melted away once I began walking! I never thought it would ever happen!
College is stressful, and long hours of study can put you in a chair for hours. Try getting out for awhile each day to walk and de-stress. I'll bet you the weight flies off quickly!
Best of luck to you!
Do well with your studies!
Cheryl
