Some while ago I wrote on here about my Dad's paranoia. He became convinced that the neighbours were waging a campaign/vendetta against us. This was because "water is coming off our roof onto their path" so they were taking their "revenge". Every day we had tales that the neighbour was sneaking out late at night and damaging our house either by "scraping out paint off" (it was very old and peeling - I have since repainted it) or by "reaching out of their upstairs window and moving our guttering" (there was of course nothing wrong with the guttering). This got worse and worse and the tales grew taller and taller in the telling (I think this is called "confabulation"?). Things got so bad that Dad wouldn;t talk to me in our hallway because the neighbours had "listeners on the wall" and he carried a fake "recording device" so that he could tell the neighbour "if you say anything to me I can take the evidence to the police". If our cat was sick it was because the neighbours was poisoning him. Thankfuly Dad had a regular checkup with his Doctor (who is also my and mum's GP) - the doctor managed to bring this situation up tactfuly (Dad thinks the nurse who was visiting us at the time reported him - it was in fact us). The GP gave Dad a good talking to saying "you must realise that you are ill, it's affecting your judgement, these things are not true and you cannot accuse people like this). Dad didn't like it...but it worked! We didn't hear anything more. So imagine my horror when this morning I got pulled outside the house with "someone's had a go at the guttering, it's been damaged". Oh dear Lord, not this again!! We think its because the neighbour's son has moved back in after being at University (for some reason the son is "evil"). I just don't know what to do. Dad is due to go to the surgery next week to see the nurse for a regular healthcheck. I am thinking that I could go and see the GP now, and see if he can call Dad in whilst he's seeing the nurse for a "checkup"...? I know Mum and I can't go through the months of paranoia we had before. It almost drove us into nervous breakdowns. I think it would be worse this time, because Dad has become more agressive recently and flies into a rage if you try to reason with him or don't agree with him over anything.
