I want to read fiction on dealing with terminally ill people.

my father is suffering from stage iv cancer. He's surprisingly okay now, but I can't accept the hope. I feel like I can't cling on to anything but depression. I don't know if this is how I'll lead my life, if he passes away I'll have to be the earning member of the house. I'm really really depressed, I have gone through a breakup just before my father's diagnosis, and my life has been going downhill ever since the end of the last year. please suggest something to read, I haven't been able to read anything properly for a while, I constantly feel like political literature (Marxist) is the need of the hour, which can change the society. nothing else is appealing to me. sorry if this is full of contradictions.
