Hi CJ,
Welcome back to the board. I think all of us here are concerned with what other people think and are just learning to figure out what we think for ourselves. I also feel it's natural for any child at any age to want their parents support, approval, and encouragement as the child ventures forth into the world. We wonder if our wings will carry us when we jump out of the nest (or the frying pan

).
My parents are pros at making all kinds of scary noises when change is in the air. Change really rocks their control boat. What was/is aggravating for me is that when the change or decision works out, they are all smiles

. I wonder "why did you put me through that?"
Now, this may not be your parents. But this is how it was for me. Also, this may seem obvious, but parents are older than we are

not necessarily wiser and looking out for us. They want a built-in free caregiver to stick around for when they get even older. It sounds like maybe you want your parents approval to move out and alas, you will not get it.
Perhaps it might help to think of asserting yourself with Y-O-U vs. your mother. Get your own approval for your own needs and do what you need to do and let the chips fall where they may.
Good luck CJ. Hugs, Seeker
