Answer:
anorexia nervosa: making themselves throw up
Bullimia nervosa: think about food a lot
Explanation:
Anorexia nervosa is an eating disorder where people try to eat as little as possible; they throw up their food, even going so far as using laxatives and enemas. So, they make themselves throw up after eating is the correct answer for the first one.
For the second one, I think they spend time thinking about food. They think about throwing up, and binging, and so forth.
