I am so sorry you have to go through this all by yourself. i can understand how you must be feeling. It’s seriously the worst feeling. I am sure you must be trying hard. Just stay dedicated not because people are saying things or you want to fit into the societal standards of being pretty. Accept yourself you are beautiful the way you are. Focus on having a healthy life, healthy body, healthy sense of self. That matters the most. And if you are struggling in terms of slow growth seek professional help. You are amazing the way you are. I am right here for you.

Hie there lm sorry about how you feel .I am also tall and huge 166 cm and 97 kgs .Ive realised that people will always talk and there will never get tired .if you get slim you will realise that they will start telling you that being a plus size suited you . So dont lose weight because people want you too .Lose weight because you want to do so .I wish l could chat with you more and we encourage each other .Pleasing people wont get you anywhere instead it installs fear in you and like a seed the fear will grow into a tree with fruits like anger and insecurity you will see everyone as your enermy.Its the least people we Expect to be body shamed by that do so .Dont listen to what your mom says instead change yourself , Read more books on how to ignore negative comments and focus on the positive ones.What they think about you is not what God sees you as .So pick yourself up close your ears and walk with your head held high when the time comes you will lose weight my dear.
