TLDR: My former friend that I educated about the existence of BPD implied that she has BPD in a post asking for money. I don't know how to feel.

I used to be friends with a girl I'll call Harriet, and her and I were very close at one point. She is the one of three people in my life (outside of therapists/psychologists) about my BPD diagnosis. Harriet and I stopped being friends when she secretly became romantic with my FP (at the time). I was furious at both of them, but more so her because she knew how much he meant to me. Harriet and I have not spoken since December of 2019. I have not spoken to my former FP since July of this year for different reasons.

I recently came across her page and saw that she was asking people (strangers online) for money. She is a small content creator (I'm being vague for her privacy) and she explained to her followers that she had to go on a mental health leave and had some costs because of that that she had not anticipated. Though her and I are no longer friends and there is zero chance of me contacting her again, I felt for her because I almost had to go on a mental health leave from school but my parents would not allow me to do so. 

The problem that I have is that she implied in this post where she was asking for money that she has BPD. Again, for her privacy, I won't give the exact language. But she had said in this post that BPD runs in her family. When I first found out about BPD and thought that I might have it, I had confided in her. She had no idea what BPD was when I told her about it. I explained the symptoms that most apply to me and she seemed to understand, but she had never heard of it before. And now she's using this disorder that has made my life hell to ask for sympathy online? I know her to be someone who lies constantly and chronically, especially about things that just don't make sense to lie about.

I went to check the post again, and she removed the part about BPD. Everything else remains. I didn't contact her about it. I just feel conflicted. I have no desire to rekindle this friendship or to help her at this point, but I don't even know if I feel bad for her because I just don't trust her or her word. I don't really know what to take from this. I don't want to gatekeep BPD, especially when it's not an easy disorder to get an actual diagnosis of, but it just feels hurtful. 

Any perspective is appreciated. I know I seem insensitive to her situation, and maybe I am being insensitive. But I'm not sure how else to react.
