First time posting and looking for some advice. My FP has found another FP and I have fallen by the wasteside, so to speak. I should first say that we both have BPD. She was diagnosed many years ago and I was diagnosed about 3 years ago. Although we both have BPD, our trait sequence is very different. 

To make a long story rather short...About 6 months ago me and my FP had a falling out. It was mostly due to my BPD behaviour in the relationship. I, of course ended the friendship right away. Then of course, went back to see if we could resume our friendship. By then it seemed too late....she had found a new FP and was completely obsessed over them. She wasn't really communicating with me via text and didn't seem like she wanted the friendship back in any way. Why?? Because she had someone new. 

I felt and still feel so abandoned and hurt. I've tried many times to explain my feelings to her but I get no validation on how I felt "dumped" and tossed aside. I don't understand why she doesn't get it. Or maybe she does but doesn't care?? 

This friendship means/meant a lot to me. Even though I consider myself a friendly and enjoyable person to be around, she is my only friend. There is no one else. And, I'm one of those people who hates being alone. I hate having no one to talk to. 

So, as things stand right now we are "trying" to repair the friendship. But things that were happening before are still happening. I know she is texting her new FP multiple times a day but she doesn't even return one of my texts. I'm at the point of feeling so angry that I just want to send her a stern email about how I'm feeling. But I'm unsure how it will be received so I haven't sent anything yet. 

Please...if anyone has any advice...I would really love to hear it. We had been each other's FP for the last 8 years...I don't know what I would do without her support. Help!!
