I'm so very sorry. Unfortunately, I know exactly what you are going through as my wife died 3 months ago at the age of 35. People down the line will tell you to get rid of her stuff(clothes, jewelry, personal items, etc.). DONT DO IT. Keep these things as a reminder of her and how much you love her. This sounds stupid, but don't wash her favorite blanket or dress. Her smell is still there. Like I said, it sounds stupid, but every night, I press my wife's favorite blanket to my face before I go to sleep and it helps.
I wish I had more advice to give you but I'm broken, sad, angry and suicidal since my amazing girl passed. I sincerely hope that you do better than me because no one should ever have to go through this.
