Michelle
I'm 5'2 I weigh 142 lbs & I'm 17. I've always been overweight and I feel depressed most of the time. I've done diets before and I eat healthy compared to most teens. 
 dk what to do. I just want to lose 20 pounds so that I can weigh 122 lbs at least. I have huge hips and a big 🍑. I just want to feel confident and happy one day and get to do all things I want to do and be good mentally and spiritually , but my weight does bring me down. If anyone has any tips or diets please comment them down below :)
