So my mom has been sick the past few days and I just took her to the doctor's office. We come home and I bring out some of this rice cake stuff that we had from new year's. I was cutting it when I realized it had gotten a little moldy on the side. I prepare to cut off that part and then throw it in the pan just to be safe. However, my mom interjects and says she'll do it. She slices a thing slice off, just enough to get the layer of mold off. I tell her that we should cut off a bigger chunk just to be safe as well as saying the microwave doesn't heat evenly so it's not really cooking everything-we should throw it in the pan to be safe. She says it's fine and she already cut off the mold, see? I repeat my concern at which point she says I can eat however I want but she's fine with this. I tell her I'm more worried about her since she's old and sick, thus more susceptible; I'm young so I'll likely be fine regardless. It's at this point that she tells me I'm talking too much and I should shut my mouth.

Now some background. When my mom thinks she's right, your opinion doesn't matter anymore. Doesn't matter what you say or how much you prove her wrong. Also, she has a tendency to disparage and say pretty hurtful things when she's angry (personal attacks). She's not a bad person but has some flaws. 

  

I get pretty mad but I just stew over it. However, it starts up again and I tell her to just be quiet and go do her own thing. This sets her off and she launches into a tirade of how she can say whatever she wants because she's my mom but I have no right to say it back. It escalates until I decide to get revenge on the rice cake. I take it out and throw it on the floor. She threatens to eat it anyways so to ensure she doesn't (and she's not eating food off the ground just to prove a point) I step in it and then throw it away. Now she's saying I just destroyed our entire relationship.
