I think it's inevitable that we pick up some traits of our parents. But, I don't think that means we become exactly like them.

My T pointed out to me a few sessions ago that I do something that I always complain about my mother doing. As soon as my T pointed it out to me, I resolved to change that behavior and have been working on it.

Besides, being like your mother doesn't have to be entirely bad or anything huge. I'm like my mother in little ways...we have some similar mannerisms and expressions. Our voices sound similar. We like some similar foods. Then, there are the ways we are totally different - she's an extravert, I'm an introvert, she is very critical and closed minded, I'm super open minded and try to see the best in others, etc. And there's the ways we're the same, but I am trying to change - like not expressing emotions in front of others. Those are just some simple examples.
