pressure from my mother..

My mother always keeps on demoralising me in everything especially when it comes to parenting my daughter. She is always saying that I am not a very good mother inspite of me doing everything on my own from managing the house, my job, my daughter's school activities, etc. I feel completely depressed and good for nothing. If I try to talk to my mother about her behaviour, she just starts yelling, defending her actions and words and starts reminding me of how bad a daughter I have been to her. All my life I have spent my time with her, never gone out with friends, instead helped her with home chores and her business. Don't know how to handle this situation, please suggest.
