I am so sorry to hear about your mother's struggle with alzheimer's. Know that there are a lot of us out here who empathize wholeheartedly.
My baby brother died at ten months old. The trauma created a massive hole in the middle of my stomach. Yet, when I went back to school in the fall, that same whole was filled with the love of my classmates. No one spoke of what happened. Their presence got me back to a normal routine like I had never been gone.
All it required for me to begin a recovery was knowing that they all loved me with their tears, laughter and hugs. My t-shirt smelled like perfume all day. So, surround yourself with positive people and simply be.
By the way, "The Rose" was delightful. Your mom has a real talent. I am glad you chose to share it with us.
