I don't think being like your mother is a bad thing. Your mom has so many wonderful qualities that you can't help but love. And this is coming from someone who has only met her a handful of times. Also I was told by a very wise counsler that you should focus on the good qualties of your parents and not the bad. Becuase if you focus on the bad then you are more likely to develop those traits and vice versa.

I know your mother.
It is a bad thing
