Hi Suraus, I’m a bereaved daughter and also a grieving mum. I’m glad you have reached out so soon, you must still be in a different time-zone warp almost.
Sure jet-lag etc but you are not alone in any of your feelings of post funeral numbness or changes in sleep patterns. You ask, is this normal? I can only reply this is your normal for right now and that’s okay. You’ve just experienced all the stresses of an overseas final goodbye, there’s a lot to process, so be patient with yourself and no hurry in doing so. But I do recommend to keep talking, there’s listening ears here xx
