I'm being charged with exploitation of funds and don't understand why.

My mom was admitted to a nursing home in January. I contiuned to pay her bill up in to late February because nobody had informed me that I couldn't until then. So then to avoid using her money I transfered $ 500.00 to her account from mine and used that money to pay bills thinking that was ok cause it was my money not not hers. I didn't pay the bills from my account directly cause they were all in her name and had her account number. I soon learned I was not supposed be doing anything with her account at all, not even adding anything, so again I stopped. I'm bipolar and have extreme anxieties so often my memory is unclear and very often after talking to people on the phone, especially if scared, panicky or upset, I don't often remember word for word what has been told me. I explained this whole situation to the nursing home and the state but am still being charged with exploitation of my mom's funds. I've never broken the law in my life. I'm 63 years old and live on disablility and after bills are is paid only have 200.00 for groceries and necessities. I'm poor, period. Also panicky and upset cause I fear jail or prison when I thought what I was doing was the right thing and when I found otherwise I stopped. I don't know what to do. I cannot hire a lawyer and have no transportation to get around. Can't even take a bus for reasons of panicking when I do. I am completely alone, I have no friends or relatives to help me, except for a sister who lives three states away and is raising an autistic grandson. I have been through so much with the NH and the state I'm close to having a nervous breakdown if it doesn't stop. I never had any business dealing with the business affairs of my mom. I don't know if this was the right area to leave this post. I apologize if it isn't.
