I don't know what to do to boost my self-esteem up.. I'm 5 feet, 50 kg at the moment. What happened is that I lost 7 kg over the summer and now i've gained it all back in 2 months. You can imagine how much i've been bingeing...right now i'm just feeling really unfit and gross. I've been crying in bed all day because i gained all the fat that i've worked so hard on losing. I just feel really helpless right now?
