hi thanks for your query
welcome to HEALTH CARE MAGIC
as per discussion it assumes that your weight change are because of your dietary changes as during your interning obviously you eat less so loose your weight and after returning to home you were free of anxiety
and eat more.
but you should consult to your physician thyroid
and sugar tests to rule out common causes.as you have positive medical history.
if these are normal than you can control you weight by simple dietary means as your dietetisian advice.
