Remora fish and bpd

I was talking to my good friend recently. She was struggling with hearing voices and I was struggling with anxiety at the same time. While hospitalized, they had to pin her down to give her a shot. She laughed and said the fight she put up was " a little borderline." I was like, "ya think." I told her I was struggling with anxiety and said my bpd popped up with it, too, making Hubby's life a living hell. It's like whatever, you are dealing with , bpd is like remora fish, those fish that are on sharks, along for the ride. What do u think?
