My friend is diagnosed with bpd and adhd, she has a strong fear of abandonment and rejection just the idea makes her spiral. She had some moments where she was upset at me and accused me of abandoning her because I texted in a dry way and other incidents like that.

What kind of behaviours will trigger her anxiety so I can avoid it? she doesn't talk about it much because she thinks shes a burden but she's like a sister to me I will help any way I can. I offer reassurances that I care about her, but that doesn't stop her from getting jealous when I'm super close to another friend. And sometimes I'll go over a day without texting and she'll start tweeting depressed stuff how no one would remember her if she died.

What small or big behaviours trigger ur anxiety and fear of abandonment? how do I avoid it
