I think I'm just an ungrateful daughter.
That's kinda sad. Why do you think you're ungrateful?
I'm always getting berated by my parents, I just want to break free from their control.
I do not know the entire story, and I also understand that you may feel like you are being suffocated. However, I still think that your parents still want to give you the best life possible, and will not wish you harm. So what I would recommend is that you talk with them and mention that you are being overwhelmed by their control, and you would want a little bit of space for yourself.
I'm sorry I'm still upset. I'm just fed up with feeling controlled. Talking with them will do no good.
On the contrary, I think talking and communicating will be the key for you to resolve your feeling of being controlled, and you won't want to feel that way for a long time, right? I'm sure your parents will understand you and will change for the better, but if not, what is important is you tried.
