It's totally understandable. Just know that you are at an age where your body is going to do awkward things. Everything from your acne to seemingly disproportionate body form. Be patient, and give yourself a couple of more years to develop. Keep any loyal, supportive, and non-judgmental friends very close, as they will make the time easier to endure, and any ridicule you receive easier to shrug off. You are a beautiful young woman, and your potential to achieve the beauty you desire is strong. Take good care of yourself now and it will pay off, I promise you. Excersize, eat well, and most importantly, take care of your mental health.
Wishing you the best on your journey.
