I am proud of you. Sometimes you just have to stand your ground. My girls have voiced their opinions with me, and sometimes we just agree to disagree... no hard feelings... but with my mother, she was right even when she was wrong, and there were times where I just had to stand my ground and speek up. Dont feel bad, and the next time you talk to her, make a point to tell her you love her. After all... at the end of the day, that's what really matters.
