i'm 16 about 5'3 and a half and i weight 174 lb 😫. i've been struggling with depression (not diagnosed yet, but have all the symptoms including weight gain) and i've just been gaining weight since 8th grade, i was 149 in 8th grade and now i'm in 11th and i try to eat less, eat healthy, work out and nothing will keep my weight down, i also have a slightly under active thyroid if that means anything ??
