Yes. They are normal. Grief has been compared as we know to the ebb and flow of the tides of the Earth. At times greif lowers, then it slowly ebbs back up around us, then it rises suddenly and almost goes past our necks and then at times, a large wave of grief will come and seemingly swallow us, sweep us off our feet and almost drown us. The key to survival is evidently to wait. Tread water when necessary. Wait for the tide to recede. We will all get through this. The Veteran's of grief here, some who have been here for many years, are proof-positive that we can survive what we are experiencing and move past it. And soon only our favorite and most wonderful memories of our lost loved ones shall remain.
