Extreme mood swings/intense personality change

Okay so a little background: this is about my dad. He was diagnosed with brain cancer (secondary) that stemmed from lung cancer about a month and a half ago. It is stage 4. On Monday he was crossing the street and he stopped. He just stood there so I said "dad?" Then he started swaying from side to side. He ended up falling and cracked his head open. I ran to him and called an ambulance. He's prone to seizures but it didn't look like one and he says he didn't have one. He has partial focal seizures so he's aware when they happen. He went to the hospital but they couldn't get a great image on the cat scan because he was jumping so much. From what the Dr could make out, there was no new bleeding in the brain. But he's been acting very odd. He's usually very laid back about everything. Even when he was diagnosed with cancer. But since the fall, he's snapping at everyone, mostly over irrational things. I'm not cooking fast enough, the food isn't hot enough (Its got steam coming off of it so that's hot if you ask me). But today was the last straw. He told me I'm nothing. I'm not good enough and I don't do enough. I tried to calmly explain that I'm doing the best I can without any help. I have a 2 yr old, an autistic brother who can't do much for himself and I have to take care of myself as well. I have to dress 4 people (including my dad because one arm doesn't work because of the brain cancer). Often I go out in the same clothes all week because I'm helping everyone else. I already know my feelings don't matter. Others have reinforced that into my brain already. But I guess I'm just asking for advice. He doesn't want any outside help like a aid or to talk to someone like a social worker. It's just me. I guess maybe some suggestions on how to get through to him? And could the fall have altered his persona somehow? I keep telling him I'm trying my best but he just screams at me. We don't have any family to turn to. He's still smoking. It's as if he doesn't care that his granddaughter is going to grow up without him. I understand cancer is a very difficult diagnose but he's just not the type to give up. I'm mostly concerned because of the sudden behavior change. I'd appreciate any advice or help I can get. 

  • Hi C.M So sorry to hear about your situation. I can't imagine what you are going through. Has your Dad got a McMillan nurse attached to him if so phone them to see if they can help, if he hasn't phone them anyway. Just because your Dad doesn't want any help does not mean you don't. My Dad was in hospital when he died (he had broke his hip) he had already become more angry but some days he was worse and told me to go away and not come back as I was working against him. I knew he didn't mean it and later he had forgotten what he said, my Dad didn't have brain cancer but was very ill so I put the personality change down to his illness and frustration. Sorry I can't help but speak to someone in his team or even his gp they may not be able to give you any information without his permission but they may be able to help.
  • Hi CM,

    What an awful situation to be in. Have you told his oncologist and the rest of his care team about it? If not, don't waste any time in telling them as these could be symptoms of his brain cancer. On the other hand, they could be symptoms of his mental state. Having cancer often triggers depression and anxiety. 

    Either way, you need to look after yourself too. Whether he likes it or not you both need some help or you'll end up having a nervous breakdown or collapsing with exhaustion - which will do neither of you any good. 

    Do you get any help with your autistic brother?  I have a sone with severe autism and know how much of a worry that can be and physically and emotionally exhausting. Have any arrangements been made for his care if/when your Dad dies? This will be another source of worry for both you and your Dad.

    I hope you somehow manage to get the help you need.

    Best wishes and Good Luck
