First and foremost, I am deeply sorry for your loss. I know what it feels like. I lost my elder sister to breast cancer some years ago. She was my best friend. I was with her when she took her last breath.
Second, I like this story and I'm glad that it is not going to be a long drawn out depressing fic. I love happy endings most of the time like now when my life literally sucks at the moment. But angsty is good sometimes...it makes for enjoyable reading when I'm in the mood for such.
Looking forward to the future chapters.
I hope you have a good year in 2018 and that nothing bad happens in your life to bring you down into a state of depession.
Great writing!!!
Cheers!!!
