Is this mental illness?!

Is this mental illness?

My mom flipped out bcuz my dog slipped out of his collar which was attached to a leash, & decided to sleep on the family room sofa (instead of in his area).My mom hates the dog to be in the house.He doesn't make any messes, and i clean up after him.She started screaming, hitting herself, hitting me, swearing, throwing things, crying hysterically, then accuses me of abusing the dog (by letting him in when it's 98 degrees outside & humidity is very high). Then she accuses me of blackmailing her bcuz the dog's inside.She says the house is filthy, even though i try to keep it meticulously clean everyday, so she doesn't flip out.She blames lots of random things that happen on the dog. She says i abuse the tv, the radio, the dog, the piano...But i did my best to avoid these things so she doesn't get into a fit. I dont know what to do.She's very beligerent at times.She has horrible mood swings.I do my best to not upset her, but it seems if it's not the dog, it's something else.PleaseHelp!

i'm 22. she's been like this my entire life, i've got used to it mostly. She is 57. She acts so odd, she's always been overprotective, my dad is slightly similar to her, but he's usually quiet and distant. The sad part is, my mother IS a doctor. So is my father. It used to be sooo much worse. A real nightmare. But they've gotten a lot better. I was away in school for awhile, and she became very depressed bcuz her mother died. So i came back home, to help her out, be with her, take care of the house. Sometimes i can reason with her. But a lot of the time, she is mean, rude, hypercritical of everything, and just has a fit. She is very resentful of my dad, and might hate him. Although she claims she loves him. But she won't divorce him. I have a sibling, but he's very similar to my mother, and he's out of state. She has been under a lot of stress for awhile from her job;she doesn't have good relationship w/ my brother.I do whatever i can to please her,but it's never enuf

Something very wrong with her.Move out soon.........Get your own life and your own place.....Take the dog with you.....
