My mom is always pissed at me for something lol I dont know your family or how it works but in my house if she starts bullshitting I fight it til i hit that wall where no matter what the arguement isnt going anywhere, then I just walk away and forget about it. I fight with my mom probably 90% of the time, and its been that way since I was about 9-10. Even though others agree that she is wrong including her husband (my stepdad) my real father, my grandparents (her parents) and even the psychiatrist she still insits its me whos fucked up haha, some things just never get resolved =\ sorry to hear bout ur fight they kinda suck
