One friend is stressing out over life and is over-eating to deal with all of the stress. The other friend says “You are so grossing me out, aren't you worried you will get fat!”

it is completely normal for people to over eat while stressing out. it's a good think that people eat while stressed, some people stress out and DONT EAT AT ALL. don't worry about what others think, especially your "friend", they are not your "friend" if they can say hurtful things like that.
