SEED have developed lots of positive resources within this website. We cover: Travel and Eating Disorders, Coping with Christmas and Eating Disorders and things that might cause anxieties for the sufferer/takes them out of their comfort zone. Remember the rule of thumb is plan and talk through your anxieties with someone you trust. Make small and achievable goals and take one day at a time.
