Toxic Family Member

My grandmother thinks she can control everyone. One day she will be nice and the next she goes off on anyone she can. She's emotionally abusive. She always tells me I need to get rid of my animals, which are the only thing that makes me happy. She tells me I'm selfish for going out to a movie one time, and she says I don't help out my family but I help them out all the time. Then once she's done being mean, she tries to buy people stuff to make up for it... and if she's mad at you she holds stuff over your head. She pays my car insurance so she thinks she has control over me. I told her to give me the title to my car back (she took a $7,000 loan out on it) and stop paying for my insurance. I'm done with her thinking I need her help! It just gives her an excuse to be mean to me. She's lucky if I ever talk to her again after what she said to me today. It's just hard to have family members that are toxic because they will always be around.
