I feel for you but......don't give up. Maybe a visit won't work out at present but keep in contact. Continue, subtle ways, letting them know you are there and they are in your thoughts.
One of the things I have learnt in life is.....ones expectations are what can cause one grief. I had a niece living with me for three years and....I started with the premise that I would not expect her to lift a finger around he House but would keep her room tidy. When she cooked a meal or mowed the lawn etc I let her know how delighted I was. I would have to do it all if she wasn't there anyway.....it meant I didn't get stressed, our relationship ran well and we didn't get into arguments because she didn't do chores.
Family are very fickle and they work from a very different agenda to us.
Good luck and keep well.
