Should I cut my relationship that I have with my mom?

Ladies do you have a great relationship with your mom? Idk where to start, I've always been the rebel child out of all 3 of my sisters me being the oldest. I got pregnant at 18 I feel like I failed my parents but my mom pretty much made me feel like shit knowing she got pregnant with me at age 15. I'm now 25 and she always has something smart to say to me. She ignores me and indirectly says things that pisses me off. I try to be in peace with her but she is a very dry and just always in a bad mood with me mind you she is a Pastors wife so I would think she had more compassion with me, she shows everyone else love except for me. She is also constantly mean to my daughter who is 6 & I think it's because she takes everything so personal when it comes to my daughter and my little sister fighting when they play (she is 3). My daughter even tells me that she thinks her "Gigi hates her" But they are children they will argue like children. I just feel like moving out of town and just limit or even cut my relationship with her. She obviously can't stand me. Her favorite is my sister who is in college studying to be a Registered Nurse. I am not jealous I am so proud of my sister I just think my mom lives in disappointment w/ me since I never did anything of myself. But I am happy with that my life I at least got my high school diploma, I am a CMA (medical assistant) I married the man I got pregnant by, we have 2 wonderful children together, I'm a home stay mom for now. What am I doing wrong? Should I cut the relationship I have with my mom?
