This is very much the opposite of my experience. Being grateful even for the losses that have brought the most sorrow, the two things at the very same time, has ripped me apart, but it's also been the only way through.
ETA: I say this not to contradict you or deny your experience. I say it in case other people are thinking their experience might need to include both, so they're encouraged to realize that, for some people, it's not impossible, but necessary.
