Pretty grim for something that’s an evergreen note.
After a certain age, around late 20s-early 30s, it is almost guaranteed that you will see your elder family members fall sick, possibly terminally.
It’s a hard time. But there’s no way in getting out of it. You just have to endure, and just help them in whatever way you can out of love and not duty. That’s the only way to get through this phase.
After that you’ll be callused enough to deal with such things anyway.
