From a psychological perspective: It sounds like a lot more is going on here than the usual mother-daughter friction, especially when you mention cursing, poor communication skills, and an unstable relationship.

You should try to find healthy role models and mentors who understand where you are coming from and can model healthy relationship behaviors so you won’t ch”v end up repeating the cycle.
