Stress keeps piling on. I'm at my wits end working as a paid caregiver.

I had been working on a case for about six months. The case was problematic since day one. I can't really post about the client and where I'm located; so, I will do my best explaining. I thought things were going okay with the case. I was told this past week that cameras were installed which wasn't a problem to me. The client refused to wear her hearing aides and would blast the TV very loud. The volume would be set at 85. I was told by my agency supervisor that this was a sitting case, and was given a care plan. I made the breakfast and made the bed per the house assignment. I was told when I first arrived that October that I could sit downstairs which was good in case I needed to answer the door. I thought where I was positioned was a little odd, but I sat where I was told to sit. I was given directions where to sit by another staffer. Well, I was texted on March 16th at 10:00 am by the house staff member that the shift had been cancelled. I called my agency immediately and spoke with the supervisor telling her I just got word that my case has been cancelled for the next day. The next day, my brother called on March 17th and told me that my niece had passed away in her apartment. Apparently, she and my sister had gotten into a terrible argument that Friday, and she died alone in her apartment. Her mother got worried and had a welfare check done and the landlord found her deceased. My niece held the POA for her mother even though she was in another state. So, now my sister didn't have a POA. I tried reaching out to her but never heard back.
My grandson had a crises. So, I haven't had much of an update on his status.
Yesterday, after my shift ended for good, I had a call from my supervisor that I missed. I was just so tired because that entire three days of commuting and that micro managing live in aide was just too much. I tried to make light on the situation, but according to the cameras, I was accused of not sitting with the client during these shifts. The care plan couldn't be followed accordingly, because the live in aide wouldn't allow me to make any changes to the routine. So, I made the bed, made the breakfast, maybe a medication reminder here and there since she took control over that as well. The staff had been leaving the medication within the client's reach until I told the live in aide to remove the medication box. She would give it to me when she ran her errands.The client came down and turned on the stove on Tuesday. I was at the stove and the live in aide came barreling down the steps into the kitchen saying that I knew how to use the stove and that I was wasting gas. I didn't respond immediately and told her that the client wanted a cup of Postum. Finally, I turned off the stove. It had been like this all week. I took the cup of Postum upstairs and asked the client if she would like breakfast since the morning was slipping by. The live in aide got angry and said that I had put this suggestion in the client's mind. I told her this is the time I normally would serve the client her breakfast. By then it was 10:22 am when client came down to eat. Thursday was just as bad.
I'm just in a state of shock right now, especially since I did what was told to do in the home even though I wasn't allowed to help the client with her personal care or none of the client related tasks. The live in aide would intervene every time. They instead just asked for another aide.
I haven't been on the board much these last couple of months because it has been a struggle these last three months. It's more to this story, and I would answer questions.
I'm just so tired and worn down right now and don't want to work with anymore clients.
