Guardianship

I am 43 and have been caring for my Mother and Father for 4+ years. I have been constantly harassed by Clark county Adult Protective Services. My Mother recently passed away after being held in a hospital bed for 2 weeks longer than necessary because APS told the hospital not to release her because they thought our home was unsafe. When they finally released her she came home sick with her first ever bed sores because they would not carry her to the bathroom like she had been going at home because they considered her a fall risk and forced her to go to the bathroom in her bed. She stopped eating because she hated the food and they rarely gave her water. She died from being there too long and it is because of Clark county APS. Shortly after she died me and my Father rented in an apartment and sold the house. While I was moving his stuff back and forth from Vancouver to Seattle I had a friend of our family watch him but she did not answer my calls when I drove from Seattle to Vancouver to get him and she called APS and turned him over for abandonment. She was obviously lying but APS was too foolish and focused on accusing me of something that they listened to her over me. They then locked his bank account so I got a job immediately to cover the rent but it’s a 2 bedroom apartment and too short of notice so I may not be able too on my income alone. We had the money from the sale of the house to cover rent and his SSI plus the money I made for taking care of him that was paid by the state, but all of that is gone over a misunderstanding and I may have no option but to default on the lease he and signed for the apartment and put everything in storage until this is a sorted out. They took the original APS agent of of the case. Her name is Taylor  and they put a supervisor Andy on the case and he is rude during the very few conversations we had. I have been writing state officials every day to complain and they are telling me that the Superior Court is involved and they are petitioning for Guardianship. What should I do to get my Fatger back? I am Durable Power of Attorney but he is being held at an undisclosed location by APS and I have not seen or heard from him in a month.
