Let's be honest, a cancer patient can be damned unpleasant to be around. He or she is most likely depressed, obviously not feeling well, and in my case moody (bitchy). There, I said it, and I can say it because I'M THE PATIENT.
And let's be frank about what it's like to be married to cancer patient: Don't expect a lot of romance. Don't expect a very clean house or good dinners. What you can expect is an argument over how you aren't there for ME. And I dare you to divorce my ass!
All that said cancer is probably hardest on the children of patients. For example, especially when I was taking chemo, I would get upset with my son easily, because the chemo had killed my patience. Children need the stability of a healthy, well-adjusted parent, and I was neither healthy nor well-adjusted. I'm not sure I am now.
As crazy as we are, please stay with us cancer caregivers. We need you and appreciate you, and we're sorry if we are pains in your asses.
If we could help it, we would.
