My husband lost his younger brother and his father in the same year, and it affected him a lot. Still does, even though it's been a couple years now. Losing one person is hard enough, but losing multiple people...well, I've seen firsthand what that can do to someone, and it's extremely difficult. I know nothing anyone can say will make it any easier, but I truly am sorry. All you can do is wait for time to heal some of the wounds, at least partially.
