Hi lakay, my younger brother passed away suddenly on Monday morning 9 Aug 2021. He was only 49 too. To make things worse he was in Indonesia and I am here in Australia during pandemic. It is heartbreaking and it will take time for your mind to process what happen. Especially when you see his things around, it just add to the feeling of loss. Try to slowly reprogram your mind so that when you see his belongings, you see in them not just him, but also yourself. Keep them safely in storage, knowing they mean something to you.
