Im being mean to my mom?

Good. You took the first step, noticing you have a problem. Can you change? hell yeah. Little by little work with yourself. I could tell you love your mom very much and that is why you want to stop. I'm sure you can do it. How? that is for you to answer and I know you are very well capable of it. You can control your temper if you wanted to. You can control your tone if you wanted to. You can control your attitude if you wanted to. She is your mother and I'm sure you know she deserves respect after all she has done for you. So think of those moments and say okay from here on now, I will be more mature and improve on my weaknesses.
