What can I do?

I'm a fresh graduate with a freelancer job. I only slept for 4 hours because I am rushing for my work. I decided to take a nap to refresh my brain but my mother scolded me because I am busy with my work and for not wanting to go out with her. It's not that I don't want to go out with her. I try to balance my work and personal life but I just can't or maybe I don't know how. I know work-life balance is very important but when I go out with my family, most of the time I think about work and there are times where I suddenly got angry if I spend too much time outside rather than doing my work. And most of the time, the clients will ask whether I have completed the job or not. I hope my family understand but they don't understand. (┬┬﹏┬┬)

What can I do? How can I have work-life balance without worrying or stressing out about work?
