Just start by taking a deep breath. Than think about all the questions toddlers and young children riddle their parents with. Think of the amount of patience it must take for a parent to keep answering the same questions or just the very numerous questions. That is what your very annoying mom has done in the past for you. She has probably done lots more too. So just be patient no matter how difficult you find it to be. We all annoy one another at some level at some time or another. Unfortunately it is your time to be patient. Hang in there.
When you start responding with kindness, even when you are feeling pissed of, you will find that you will teach your heart to accommodate or influence her to change. This kind of a feeling builds up when you don't recover from the first time you felt irritated. You keep harboring some feeling of resistance to what she says to you. You may realize that it will most likely be you who has changed about what she asks of you rather than her changing what she says.
