I just don't no what to do. my lovely mam has just changed so much. she can be really nasty and very selfish.my dad has her 24/7 and I worry for him. he is 80 now and is finding things really hard. we help as much as poss but we all work. for the first time yesterday I heard my dad admit he doesn't no how much longer he can take it. he does everything round house. she doesn't even cook now . he has to do everything . at night times she wants to go sitting in other peoples houses and my dad is worn out. I really worry for his health
