I am spending Christmas with my parents. Normally that isn't a problem but am worried about Christmas triggering my bed. Because my mum tends to leave nibbles out over Christmas and it's easy just to pick at them and therefore eat a lot. My dad then has a go at me for being greedy over food (especially as my mum does a lot of buffets over Christmas which has enough food to feed the 5000) which in turn leads me to restrict my fluid intake as a way of coping. If my parents see me not eating then they have a go but it's easier for my fluid intake to be restricted/go unnoticed hence why my fluid intake goes to pot. It's a lot easier at home where I feel more in in control. Help?!
