I'm looking for some friends, hopefully teenage like me, around 150 lbs 5'3 preferably same measurements and weight as me trying to lose weight about 30 lbs so. People that have had success losing it would be GREATLY appreciated. I don't know what to do with the multiple online sources and how to stay on track with my busy schedule and almost all my food is stuff that i can only eat foods i really find in the store, no home cooked food i can make myself. I dont feel good about how i look, and its really bringing me, my family, and my boyfriend down. so please help!!
