But if my health made me feel like I was going to miss them (or worse: derail them), then I would be forced to admit it wasn't for the best for me to keep going as is. If I was sure that was the case, it would be easy.

Conversely, it's easy to examine "from the outside" someone else's situation and say they should keep on going. I'm not so sure I could endure what TFA describes either, especially since it's probably hopeless, and especially after watching my own father sit dying for days in a hospital after his heart attack while the doctors poked him to make him move to show my mom he was still alive. It was gruesome and he died anyway.

When you’re ready, you’re ready, but people should have the option of continuing if they want.
