I'm 24 and I've suffered from an eating disorder on-and-off, but am currently just on the borderline of the 'healthy weight' BMI range.
Long story short, I find that certain types of people/situations are negative influences for my own self-perception and consciousness of my own diet. For example, people who are vary concerned about their calorie intake & diet can make me feel stressed: I can't help but compare my own diet, and feel guilty about my own food intake, and feel compelled I (sometimes without meaning to) restrict my own calories more, lose my appetite etc....I'm much happier around people who are more relaxed about food; they may be fairly slim and healthy, but they aren't overly restrictive.
Anyway, my younger sister used to be a little overweight, until she went to university and had a more 'normal' diet. She then lost some weight, and is now a healthy weight. She seems to me to be quite focused on her food, buying everything low calorie & zero fat, not eating foods she used to enjoy.....Hence, I feel quite anxious and unhappy at home, and avoid going home when she's there. I can't control others' eating habits, nor do I want to, but I can control what I do....So I avoid home when my sister's there. My parents criticize me and shout at me for this.
I've tried explaining my feelings to my parents but they are not very understanding.
I just feel my sister is a negative influence on me and I'm already bad enough with my dietary habits and scrutiny - I don't need more of it thrown in my face at home.
How can I cope with this situation? I have to stay at home for another week or so.
