When sick, i can't stop eating! i get pain & reflux, but continue to eat. does it mean i'm not getting the right nutrients, or is it something else?

Might be emotional: I can't guarantee that nutrients are unrelated, but it's more likely an emotional reaction. You don't say what kind of sickness. Anxiety & mood disorders can directly lead to strong drives to eat, while any type of (medical) illness can lead to a wish for caretaking and nurturance. Binge eating, especially of "comfort foods, " can be a way to satisfy this emotional need. Not a good idea though.
