Should I go NC with my parents?

I (29f) am considering going NC with my parents (65F and 69M). I lived with them until three years ago. Now I'm renting but I come back to thir place every weekend. I struggled to find work because I'm disabled. When I did eventually find a job, I had to quite for medical reasons or was fired because I missed work for medical reasons.

I stated my current job job about 6 months ago. From the get go, they installed this fear in me that I'll get fired because I'm not devoted enough to my job. In general, they think my job and money is their business. They are helping me buy a condo, so I am partially financially supported by them.

About a month and a half ago, I fell on my way to work and hurt my lower back, my elbows and my knees. I was on sick leave for 3 weeks, returning to work at the end of November.

Last week the pain came back. I went to urgent care. The doctor told me to rest for five days. My parents told me to go to work anyway, because they'll fire me. I didn't go back to work today. My mistake was calling my mom because I needed her to take a picture of a medical document that I've forgotten at my parents' house. She asked me if I'm at work. I initially said yes, because I knew she would be mad at me for not returning to work. She pressed on why I needed the medical document, so I had to confess I'm not at work. She got really mad at me for lying. I tried to explain that I can't talk to them openly. When I try to say my job is none of their business, they say it is because they have the right to be worried about me. It's almost like they're gaslighing me. So I had to lie to keep them out of my business.

Now she insists on having a talk when I come back to their place, saying that our whole relationship is based on lies. I'm considering not going back and going NC with them. I admit that the timing is not the best, because my dad is at the hospital and his birthday is coming up. But I just know that they will keep gaslighting me.

The problems with it are that I won't be able to see my grandma (89F) who we usually go visit on weekends. She lives far away and I'm not able to drive there by myself. My brother (25M) also live about three hours away and I only see him on weekends. Also I'm pretty sure they will stop transferring me the money for the condo. I know I sound super ungrateful, but they're not people you can talk openly with. I can't just tell them "you've gaslit me in such a way that I had to lie to avoid it".

What should I do?
