How do you deal with death in this situation?

I have a family member dying, and two others close to it who have chosen to expedite sorting out their finances.

This results in quite a significant inheritance for myself, enough to retire.

I do feel sad for the situation, seriously. I can't explain it, but although I have distance to others, close family members mean the world to me.

But it's given me hope for the future, I know I have less to worry about. It's hard to hide that I'm in a way in my mind going to benefit - it's just a fact but it has to come up at some time, and it's just the worry of approaching it I guess.
