Is it bad to become like your parents?

Ask your mother what she did to avoid turning into her mother!

Who, after all, has faced a more similar problem?  Of course do exactly what she says.

Alternatively, probably you are already like your mother.  Almost certainly you are very much like some time-slice version of your mother. 

How would the younger version of your mother have felt about how she turned out, if that younger version could look ahead in time and see her 2007 self?  Your words suggest "not so happy," when you write "the prospect of me ultimately turning into her also scares me to death. Frankly, I do not think she would like it either."

So deviate from her, and deviate from how she would have felt at your age.

In other words, embrace turning into your mother.

Seriously.
