My mom doesn't like me (M22) staying on screen even

I love her and knows that she doesn't have any ill intention for me. But she is dismissive and always crossed over me enjoying or surfing on internet, playing games and whatever.

This has always been the case , even after she knows that I have genuinely studied hard and doing something productive everyday she would always resent and try to bully me out of it.

I am willing to do chores and work , but it often feels like she makes me do things not bcz of the fact that I need to contribute in house but bcz she sees me having fun on my phone or streaming some video.

If I get a fixed set of duties and schedule of all the things I need to take care of I will, but a huge part of me dislikes doing chores with her bcz she is always thinking my life is easier when I was bullied , bodyshamed and I had to go through the same academic hardships stress like any individual would.

I know she has worked way harder for where she is but she never respected me for being a straight A student neither provided me emotional support during my academic setbacks.

All I expected from my mom is not ridicule me for spending some time on my phone after seriously doing something productive , like I hv been wasted and lazy like a couch potato all day.
