Trapped and isolated.

OP, it's very hard to understand your situation, you write it like we know what is going on, we don't.

You finally posted that it is your father. We didn't know who "him" is.

As cwillie stated unless NZ has some laws that adult children are responsible I wouldn't do it. Sounds like you had a rough childhood(sorry to hear that), but taking care of parent who you love and gave you a good home and childhood is difficult enough, you don't want to take care of someone you resent.

There must be some agency that deals with elderly people who have no family or no family willing to take them.

This is your father who abandoned you when you were 12? Where did you go at such a young age, and how did you get roped into caring for him now? Unless NZ has filial responsibility laws I can't see how you can be forced to care for him, and even then I doubt that hands on care is required. Realistically, if he had no children what would happen to him? Imagine what would be the worst that would happen to both him and you, if you find a placement for him and walk away? You can still care for him in a supervisory way and get on with your life; even if all your money has to go to his care at least you would be free. Seriously, this could go on for years.

social services said im on the 2 month waiting list and im in new zealand, your basically on your own here, even when i get assessed ill probably get an hour a week whooped de doo i wont even have time to wind down,, alzeimers and dementia group for caregivers here will take them to a group he wont go he'll probably tell them to stick it up there royal irish arse,,,, i have one brother in australia the only time he has been interested is when i put a pic of dad on face book free to good home he was offended and asked me to remove it ,,he has nothing to do with him either i had no takers by the way.hes knocking at my door now and trying the door handle over n over talking to himself its like a horror film

Is this your father you are taking care of ? Do you live in the U.S.?
Sounds like a struggle for you and I can only imagine how difficult caring for this person must be.. Can you call Social Services to help you get some help ?.
Please give us more information when you get the chance..Meanwhile..I'll say a prayer.

The biggest question I have is how can you get un-trapped and back in with society. You sound most unhappy. What is keeping you from moving on, since you have no ties to this person? Please tell us more. You sound like you're at the end of your rope with him.
