Why I have stopped writing for a while

So I had learned that my brother has passed away due to a disease. I never got to meet him, and I had asked my mother if I could and she told me that he had passed. We don't know them name of the disease but, what it did was, it made his muscles stiffen over time. His heart, lung, etc. It was tested that he would not make it past the age of 5. I have been down about it, especially after learning that they don't even know if he is buried or cremated or somewhere who knows where. I am his little sister......forever and always.....
