How Do I (28F) Cope With Going No Contact with a Parent (48F)?

r/

Ever since I can remember, my mom has always been insecure and lacking in maternal instincts. She has never not been in a relationship for as long as I have been alive (28 years). She has a tendency to choose the men she is dating over her children (I have 2 younger sisters, 24F and 16F), even if it means putting her children in harms way. As a result of my mother’s neglect and lack of parenting skills, my youngest sister (16F) has dropped out of high school and is now pregnant.

Due to recent events and some of the aforementioned reasons, I have finally agreed it is in my best interest to go no contact with my mother. Although I am angry, it does not make it hurt any less.

TLDR: I (28F) finally had to cut all ties with my mom (48F) after she has repeatedly made it clear that the romantic relationship in her life is her main propriety. How do I cope with losing a parent who is still alive?
