Ah crumbs you have only been diagnosed a week, your body has suffered a major assault and you need time to recover, it’s not a quick recovery it does take time as your body slowly adjusts to insulin and your cells start to recover and replenish themselves. Please read my thread about what every t1 should know.
People say things with the best intentions however until they walk in your shoes they will never know how it feels, you are grieving your health and diagnosis and will experience many emotions, but take it one day at a time and reach out if you need anything at all, I remember my diagnosis all too well.. best wishes x
