Sister told me my narc mother cries about me

My sister is fully supportive of me since I’ve been no contact with both my parents. Today she told me that my narc mother cries about the fact that I’ve left. She told me that my mother was crying really badly at her father’s funeral mostly about me. I didn’t go to this funeral since I had no relationship with my grandparents anyway.

I guess I feel bad because I’m not like her. I don’t like to make people cry and I do feel guilty a tiny bit. But it doesn’t make up for anything and everything she did to me. And my sister told me that sometimes my narc mother talks about me in a sad way. I guess I’m just like 🤷‍♀️ you made your bed now lie in it. But at the same time I don’t want her to cry

Edit: I think people think my sister is in league with my narc mother. She’s not. She doesn’t really talk to my narc mother much. When my narc mother was crying at her dad’s funeral about me, my sister turned the other way. She just heard and saw her crying with her friends about me
