NDN is an elderly man living on his own, he has a daughter who visits and I'm on good terms with. NDN's health has declined rapidly in the last couple of months, he's become very confused and has been in hospital at least once in recent weeks. His daughter is around as much as possible but has her own family, job etc so NDN is alone a fair bit of the time.
Now to my issue, NDN keeps getting confused about which house is his, he's still going out for his walk every day and when he gets back he tries to unlock my door with his keys. I'm aware I am reacting disproportionately to this because I had a really nasty 'home invasion' type burglary at my last house but I'm afraid to open the door when this happens and end up shaking and getting myself in a real state until he gives up and goes away.
This is making me feel awful on multiple levels, firstly i feel bad for not being more helpful, I have been helping up til recently (shopping, calls to landlord over boiler issues, calls to daughter when he's had problems etc) and if I saw him outside confused I would try to steer him home, it's the fact that he's trying to get into my house that's driving my reaction. I'm obviously worried that he's wandering about confused but he's still a big guy (and I am tiny) and I'm worried he won't be convinced it's not his house and push his way in, or get aggressive because he thinks I'm in his house. So I feel bad that I'm effectively leaving a vulnerable man to fend for himself and I'm struggling to not feel responsible.
But then there's the effect on me, it takes me ages to calm down after it's happened and it's starting to make me on edge in my own home, I feel like the PTSD I had after the burglary is creeping back in. I will speak to his daughter so I'm not really looking for practical solutions, to be entirely honest I have enough shit of my own to deal with right now so will have to hand over solving the problem to her, I just want to know whether I'm being totally U to feel it's not safe for me to open the door when he's obviously so confused. He can hear dogs barking inside which clearly aren't his so me saying 'you don't live here' may not be enough to convince him he's in the wrong place, and what then?
