I have a friend who is going through some emotional turmoil and I don't know how to help them. She's a great and dear friend to me and it hurts my soul seeing her like this.

A little about her. She's misanthropic, nihilistic, and emotionally unavailable. I think she could be labeled as a "quiet pwBPD" based on the time I've known her. She always says "I'm fine" or "It's alright" and a lot of times dodges questions. She has stated that she has liked me more than a friend and the pieces fell where it may.. I fell in love with her, but we're both not ready for a relationship or anything.

During my time with her as my friend she has always told me, "You don't need to help me", but I've always reassured her that it is genuinely what I like to do, even if she doesn't like the idea of me helping her with whatever.

I have always told her that I am there for her if she needs anything. Food, drinks, or if she needed to vent or talk about whatever (low chance of this happening, but it's worth a shot).

What could I do to continue further helping her? I would like someone to talk to or at least have someone reach out both pwBPD and people with similar experiences.
