Book that helps to deal with the death of a loved one and with life.

Hi. My mom passed away very recently. And I'm living with my dad. I watched yesterday the movie "Caramelo" that kinda helped me. But I'm having trouble dealing with death since I was young. How life has an end. And now after my mom, I think how could I leave my dad? if he will be alright? And I have so many thoughts on that. So If you know any books that could help with grief and a better view of death, I would love to know. I know life isn't easy, but now I feel like a burden for my dad instead of helping. Since I'm the last child home, I just want to get better.

Sorry if there is any mistake in english since it isn't my first language.
