Weight loss - it's caused the most damage to my health and means I have to stuff down far more food than I am comfortable with, all day, every day, worsening my other symptoms in the process. I can only occasionally give myself time off from the pressure to keep eating more. And it's never ending because even when I reach a healthy weight I have to keep stuffing myself because I usually just end up losing again - like a "yo-yo dieter" but in reverse.
