Burial for Sebastian James

My name is Tina James, wife of the recently deceased Mr Sebastian James, who passed away unexpectedly on the 24th of March 2021. Coming home from work at 17:30, we had dinner while watching the football match. We later went to bed  at around 22 pm. He excused himself and went to the toilet, though after not hearing from him for quite a while I went to go check on him. I found him on the chair, sweating profusely,  I panicked and quickly switched on the fan. I could see he was in a lot of discomfort. He struggled to tell me to call 999, which I did.  He was running out of breath. The respondent advised me to preform CPR on him while waiting for the paramedics. When they arrived, they  took over. But my husband passed away right in my presense. No matter how much we tried, he wouldn't respond. We couldn't bring him back. My heart was filled with grief.  My entire world, gone. Where should I start? For a student working parttime, I would never in my wildest dreams imagine my husband dying so soon without any life insurance. 
I request help to give him a burial, one he truly deserves. Thank you, each and every penny is apperciated.
