My empathy for your losses.
I had a friend last year had the same issue. His house burns down due to short circuit and took over half year to rebuild it. I'm glad your family is safe. It is true that everything can rebuild as long as we are still alive. I understand it is hard, but the time will pass.
Keep calm and have a safe journey back to Japan on Tuesday.
@legendchew thank you for the kind words. Life goes on and we have to work harder, but never give up.
