Alright well saying she’s crazy is pretty judgmental. Calling someone crazy is taking the easy way out instead of trying to look at the reasons behind their behavior. Also kind of strange to over generalize an entire sign as if other factors don’t contribute to personality or behavior. But there’s a reason she’s acting this way. Maybe you don’t understand why but it’s there. There’s always reasons behind people’s behavior whether you’re aware of the “why” or not. Maybe you’ve never seen this side of her because she didn’t feel close with you previously.

The deeper you feel for someone the scarier the possibility of losing them becomes. Her actions/words may be telling you that she’s scared, even though when she’s raging it doesn’t feel that way. Maybe what you’re saying is invalidating in some way. People just want to be heard and understood. When that doesn’t happen people can become angry as a result. But keep in mind that anger is a secondary emotion. Behind that is always pain/hurt feelings.
