I am so sorry and saddened to hear of your loss. My mother died eleven weeks ago I have been distraught, so I can only imagine your pain. I felt as if I had had my heart ripped out. For myself I let my self feel the overwhelming emotions and cried an ocean daily. My mum had dementia for 26 years and I lived with her for eight years. I feel empty within. After a few weeks friends call less, so I joined a gym six weeks ago which is helping me tremendously and also daily walks in nature. I hope you look after yourself.
