It sounds like your friend is trying to project a certain image or persona, perhaps because she finds it empowering or intriguing. People often seek to express themselves in ways that reflect their personality or how they want to be perceived. It’s possible she’s looking for attention, respect, or to feel more confident.
Your concern about her potentially pushing people away is valid. Sometimes, an intense demeanor can be intimidating, and it might lead some individuals to feel uncomfortable or distant. It might be worth having an open conversation with her about her motivations and how she feels about that risk.
Encourage her to find a balance that allows her to express her intensity while still being approachable. Ultimately, it’s important for her to stay true to herself and feel comfortable with her own identity, whatever that may look like.
