I'm sorry for you loss, Madam. By reading this I can feel how much you and your husband loved each other. By seeing all the bruise and blood who can stay calm? They say life is a journey, I can see you've had a good one. They may try to cheer you up, I say time pauses here for as long as you need.
I'm having a similar situation, I had a gene test and it says my son has a super high chance of a type of cancer, and there's no way to prevent it. I'm worried, I take him to get tests every half year, but I don't even know if this will help any.
