@aliali No doubt you are seeing there are so many things to do, and perhaps it is overwhelming. Learning to adjust your life now without your father can seem impossible some days, doesn't it? Please don't think it all has to be done at once! As others have said, it is a process. Perhaps pick one or two things you have done most days, that are a habit, and make sure you do that. Having something in your day that is "normal" will help you, I bet.
