I want to join in, I wish you lots of strength and that you can overcome the illness. All the very best!
As a single person, of course, the financing rests on my shoulders. If such an illness were to affect me now, I would also have a serious problem. For a while, I could probably compensate for the loss of income, and the family would also support me (and would be able to do so).
I have not secured the case of my death. Why should I, the father of the kids has his own house. They would live with him anyway.
