Hello David,
I am so sorry to hear of the loss of your Brother. I can honestly say, I feel your pain, and what you are going through. My older Brother, just got diagnosed with inoperable brain cancer. He only has 4 to 6 months to live. I cannot wrap my head around all of this. Even his Doctor's cannot find a cause for this. The poem you wrote was very touching, and heartfelt.
I also wrote a poem about my brother at 3am... The words began to come to me, and I raced to my desk to write them down. For a second it made me feel good to type those words, and then the sorrow came back.
I pray for you and the loss of your brother.
You are in my prayers. below is the medium link to my brothers poem.
