I have over-paranoid mom who sees almost everything in a bad way. I know she maybe trying to protect the family member but she's being too much and i'm so tired with it. I'm the eldest child, 22 but she won't let me to work if the place is too far from home and finished at "night" ("Night" in her mind is anytime > than 5 p.m, so if i some home at 6 p.m it's considered as "too late")
Coming home even at 7.pm is incredibly rare for me

Thus she's always worrying and saying about unnecessary things almost every 10 mins such as "why does he (my younger brother) not at home yet?", etc meanwhile he got extra class or something and she obviously knew about it. Also she's always think as if we're gonna get an accident or something worse outside or whatever. So all she does is like trying to force everyone stays at home as long as possible.

I tried to talk about this with her but she's also very stubborn and think that she's always right all the time. All the time.
So far discussing about this with her is like talking to a wall. She's always making so many excuse to make herself seem right about this, including in front of others.

And now, she's trying to convince me to quit my job by saying she doesn't feel safe if any fam member isn't at home and some excuses that she's right about it. I feel sick because it slowly ruining my life, i missed some good-payment jobs because of this. I'm not that submissive but i figured out that she rejected some job offers by herself without my consent wth.. I didn't even know about that

I don't know how to deal with this and feel so annoyed. "Talking" doesn't work anyway. Asked my grandma(her mom) to talk about this but sadly it was useless too. And the worse thing is her behavior caused more family issues making the atmosphere here somewhat bad and uncomfortable. I really want to move out but with my financial condition now it's impossible.. Thus i have my own problems and stress

What to do then?
How do i deal with my mom? i'm confused
