TL;DR
I work in a family business, so my parents and me are all at the same place at work. Today went to a cafe right opposite to our workplace, to have some pancakes. While i waiting for my food, i got a call from my mom, she asked me where I am, i told her I'm at the cafe, she said she can see me, and she's asking why am I simply sitting there with my phone, and she said that if dad sees me he will get angry. I felt so uncomfortable, I'm 24 years old and my parents have a problem with me taking a break. 

This made me realise how bad it is, it's not the first time something like this has happened, several times before this my parents have asked me why am i always on the phone. There are cameras at the workplace, sometimes they sit and watch. This one time i was at work. And my dad sent me a screenshot of me sitting on my phone and he questioned me. I use my phone only when I have nothing to do. When I have work, i do it. 
No matter where I am, i always feel like they'll be watching me somehow, when i go out with friends i worry about my parents passing by, when I'm in my room at night, even tho they're asleep, i keep getting worried about them barging in. 
My life is already miserable because of them, i have other anxiety issues because of them, and now this. It really feels like a prison with no way out.
