Thanks for your kind message, JimsWife.
This past week has been particularly trying for us as a family. My father was released from the hospital on Saturday and has been a complete nightmare to deal with ever since. I don't think he came to terms with his diagnosis before he began treatment or fully understood what the future would hold (as in taking responsibility for his stoma), so now he's just lashing out at everyone trying to support him, blaming everyone for his situation, and being generally nasty. When first diagnosed, I tried to convince him to go to the cancer support group at the place where he received chemo (and suggested by his oncologist), but he had no interest. I live 70 miles away and have a demanding job, but this doesn't seem to matter to either of my parents - they just expect me to drop everything when they need something, so I get stuck dealing with paperwork, making calls, and figuring stuff out. Of course, I'm willing to help, but it has gotten to a point where they're simply not willing to help themselves - they just call me and make me deal with whatever the issue is, without even trying. My dad wouldn't let me sit in on the session with the ostomy nurse ("You won't be dealing with this"), yet Saturday night it was me that he turned to when neither he nor my mother could remember how to connect the night drainage bag. He insisted that the included adaptor was incorrect (because what he had at the hospital was different) and I ended up calling the hospital and making a round trip there to confirm that the adaptor was correct (at 10:30 PM). I got home only to find that he thought he'd popped his staples (there was blood on his shirt) and wanted to go to the ER. Another round trip and 3 hours later, we found out it was just seepage from the healing wound.
Can anyone offer any advice? I'm considering calling his oncologist (which whom he has an appointment next week) and telling him that my father's mental health is not good. He keeps saying he's "done" and "fed up" with everything, and dragging my mother into his downward spiral.
