Not understanding my mother's behavior? Could she have dementia?

I moved in with my mom last year. She is 65 and disabled. She had a real rough year last year. My mom was in a nursinghome but we got her out to come back home to her house. She needs someone here at all times because she cannot walk and needs help with daily activities. She cannot even cook.

I am here at all times with my mom. My mother treats me like garbage. She tells me what to cook, I cook she will not eat. If she do eat the food is not up to her standard. I buy her something it's either too big, to small, the color is ugly or whatever. I tell my mom to do something to help ease her pain she won't listen to me. Mom gets on the phone with her friends and she listen to everything her friends tell her even if it is not going to help her.

My mother uses a potty. I clean the potty out when she makes a bowel movement, I clean her room, wash her sheets, and help her with her bath yet she let her friend fill out her paperwork for her health insurance and I her daughter.

One of her friends called Adult Protective Services on me last year for spite and now my mother acts out and cries and I get upset. I am fearful that one of my mother's friends may make another false report. I am even afraid to be alone with my mom because she cries and has fits when she is alone with me. At times I believe my mom is faking. One time she acted out I grabbed my phone to record her, and she immediately stopped. I was homeless before I moved in with my mom and I have nowhere else to go. It has been a living hell since I moved in with her. My mental health has gone down. I don't take care of myself like I use to because of what I am going through here.

My mom gets on the phone, call her friends and tell them sob stories. She wanted to do Bible Study at 5 am knowing she is disabled and on medication for her disability. I told her no she needs to rest. At times I believe she puts on, but it is hard to tell, she will not let me go to her doctor with her. My head feel like its about to explode.
