Lost my Dear husband after a week of marrying him

My beloved Husband was only 59 , we managed to get married on 26th June and the following week he passed away , I cannot believe he’s gone , he was diagnosed last August with stomach cancer that spread to his liver after 6 rounds of chemotherapy he went in remission after Christmas , suddenly in his birthday 4th may he had a turn not remembering the year etc was admitted to hospital for scans etc and unfortunately they found it had metastasised to the brain and back to the liver , he managed to have a week of radiotherapy but unfortunately on the 15th June the oncologist told him he couldn’t have any more treatment as his enzymes were too high and 2 weeks and 4 days later he fell asleep forever leaving 4 of our children and all his loved ones , I have no idea how I have got through 4 plus weeks without him , I’m lost and even though I have friends and His side of the family I still feel my life has gone crumbling down
