Judging myself for doing my own routine when my mother needs my constant listening and company

I live with my parents and my mom is someone who likes for me to be with her downstairs while she is cooking or doing stuff.

She asked me to talk to her constantly which I try all the time.

But sometimes I need to be upstairs doing work or listening to coaching calls and cannot do that downstairs while talking to her.

I find that I feel guilty because I am not giving my all to my mother.

I am 31 years old, female, single.
