Do indeed to lose weight

Hi I'm Bonnie and I'm 13 years old. I weigh approximately 45kilos and I have a small tummy. People at school always say I need to lose weight or I'm fat. I honestly don't care about what they think but do you think at the age I am is my weight ok? And on an unrelated topic when you exercise is it natural to get excessive sweat in the vaginal area as that always happens to me. Please give me some answers

💕 _It would definitely mean the world to me_ 💕
