Moon,
Your weight gain is GREAT !! Keep up the good work. I know how difficult it is because my daughter (age 12 - 68 lbs) has always struggled with her weight and had g/tube put in when she was 7. I also feel for you (as I do my daughter) when someone says you're "skinny" because neither one of you can help it. Don't listen to others insensitive words about your weight. I tell my daughter all the time to just let it go because they don't know any better; she would never go up to someone and say "good grief you're fat - what do you eat".
