Help. Me. Gain. Weight. Seriously.

My mother litterally gave me the nick name the human garbage disposal cause she didn't understand how i could eat so much and still end up the same weight or loosing weight after cleanin out the fridge. Now she thinks im not eating (which i do alot) since i moved out still stuck at 110lbs after movin out 2 years ago. What am i doing wrong. ;-;
