That was really quite something, really deep and thought provoking
I really like how you used second person, it made it seem for personal to the reader and even to the character because, as you use the writing it down reference at the end, it made it feel like she was letting all her feelings out.
From the critical side though, there was a few tense mistakes but they were hardly noticeable. But for example, "You remember one day he lied down next to you in your bed" should really be "You remember one day he lay down next to you in your bed" but that's really it!
You have such a beautiful writing technique, keep it up xD
