Mom 12/18

How can I better myself at holding space? I am working on my thoughts but I have the hardest time with my mom. I have been changing my thoughts but my opinions are always in the back of my head and it bothers me that she doesn’t take care of herself. She vents and complains to me everyday. Ive excepted that she won’t take any of my advise but don’t know how else to think of her.
Thank you.
