DH has mri scan tomorrow to assess his (incurable) brain tumour, results thursday. everyone is stressed, 14 year old son is shouting and irritable and refusing to clear up after himself, 6 year old daughter screaming at top of her lungs about something, 11 year old plugged in to some game to escape it all. finding it hard to cope and I'm being a crap mum, shouting and moaning . life just seems so hard at times. want to hide under my duvet for a very long time.
