Most Helpful Guy
All you can do is take it day by day, hour by hour. Try to spend as much time with friends you can trust. Night time is always the worst, when past wonderful memories come back to haunt you. Try to keep as busy as possible, but your attention span will be limited, so don't take on mammoth tasks. Read a few pages of a book, then go out for a coffee. Have a short walk. Do as many small things as you can, to keep diverting your mind away from the grief.
I went through this 10 years ago when I lost my father. It will take time, but I promise it will get better. It'll never go completely, but you will learn to live a normal life with it.
Take care, stay safe!!2
