How do you imagine you would feel if you were super depressed and received bad news?

I was pretty depressed these past few days and just today someone told me that my grandfather died (the father of my father). We weren't that close and the moment I received the news it didn't effect me. But now and after I started thinking about him and that I can hear his voice in my head, I feel even more depressed... life is not giving any reason to be happy 😢💔
