My brother passed in August 2019 from tonsil cancer which then spread to his lungs and I was there with him at the end and saw him take his final breath. His death was the first death that I had witnessed but not the first death I had experienced. I have already lost my parents and had seen both their bodies at funeral parlour. I am haunted at night by my brother's death and have now been diagnosed with insomnia. I cannot shut my eyes without the image appearing in my mind. I have tried sleeping medicine which worked initially but now have no effect at all. Has anyone experienced similar to me and can give some advice or ideas on how to move forward? I feel stuck in limbo and unable to live my life as normal as my thoughts are erratic and I'm so so tired.
