My parents are 81 & 82, my father was in a bad car accident...

My parents are 81 & 82, my father was in a bad car accident on 9/11/07 and his health worsen, my father has always been the most motivated person I HAVE EVERY KNOWN. They live in a log cabin on 34 arces that my father built. After the accident my dad couldn't hardly go. So in October of 2007 he said he wasn't felling right and we took him to the hospital and he hasn't came home yet. The doctor recommended that he go to a Nursing Home for 2 weeks for physical therapy because he got to the point that he couldn't hardly go. He walked himself into the hospital and he hasn't walked since. He had galt on his hands and then as time went on he couldn't feed himself, and he quit talking. So the end of December 2007 they recommended for him to see a Neurologist, one look at him and she said that he had Parkinsons', they started him on Parkinsons' medicine and he really started getting alittle better and then he ended up with a bedsore on his buttocks that you could stick 4 fingers in it and so they sent him to another hospital for that. Now he doesn't talk to us and his body is all curled up. He looks very sad. My mother lives alone and she also has Parkinsons', she doesn't drive and she has to depend on her 3 children which none of us lives in the same city as she does. I'm the youngest and the closest one in distance to her, my brother lives 45 miles away and he's been getting cemotherapy due to cancer and he has his own business and my sister lives 60 miles and she doesn't work and her husband doesn't work. I worked up until February 2008 and no longer working. I'm the one who does most of the traveling my mother to see my father now he's approx. 100 mile trip for me. I get very stressed and my husband and I seem to get into it alot cause my brother and sister doesn't do as much as I do, but in there words they do just as much which isn't true at all. My mother wants to bring my father home and I told her that I would donate 3 days a week to take care of him but I cannot get any straight answers from my siblings. My sister says that she will not change my father pants or bathe him cause she just can't. My mother for some reason I have no clue appointed my brother Power of Authority. I'm the one that takes her to the bank the grocery store and doctor appointments. My brother visited my parents maybe 3 times a year and not to long ago me and him got into it and he gave me a black eye cause he said dad gave him all the tools in the garage. My dad isn't even dead yet and those tools should have stayed there so we can use them to taake care of the place. That's what we got into it about. My mother, sister, brother, brother-in-law, and my brother 2 boys was there when this happen. I got hit in the eye and no one did it and it had to be my brother cause his sons were holding me back , whay I have no clue and my brother hit me in the eye but no one seen it. They act like I made it up. My husband is very anger in all this and he doesn't want me around them. My brother has never said he was sorry and my mother says it was all my fault and they are all sticking up with him. I was going to press charges against him but since my mother is going though enough with dealing with my father and she seems to think that if we get him home that he will get better, but he won't, he will never be that same person. My mother calls me for everything. What am I to do. I feel like I'm goind to have a nervous break down. I want my dad home again too but I can't take care of him 24/7 and my parents can;'t afford to pay for private help. Could you please give me advise...
