Guilt tripping mom

I need some advice, resources or maybe a good book on how to set boundaries with my mom. I love her but her behavior is causing me a lot of pain and anxiety. Specifically, she emotionally manipulates me and uses guilt trips, assumptions, leverage, and tantrums to get what she wants. Everytime she does this I feel frustrated and angry, and it takes my energy away from myself and my husband. When she says no one else is helping her to guilt me into doing what she wants, while their actions have nothing to do with me it's still true. Many of our family members have distanced themselves or just haven't spoken to her in 20 years, including my siblings. I am over 30 years old and going to become a mother myself soon. I need help protecting my baby from this because I can't do this any longer, and won't stand for her doing the same thing to my child. Has anyone dealt with a guilt tripping mom? What did you do about it without completely cutting her off and did it work?
