To me this sounds like a sensitivity thing that is related to fear / anxiety / worry. And yes, due to the nature of that worry (relationship abandonment / betrayal, etc), it could be related to your BPD.


Confession: When I was around 17-18 years old, I had a massive fear of being / becoming schizophrenic. It was like the worst thing I could think of at the time (sorry to anyone who is schizophrenic and may read this - I don't feel that it's the worst thing at all anymore). I went through a lot in my teen years, but this was something that consumed me sometimes. While it's not the same thing subject-wise, the topic you brought up of having a worry / intense sensitivity to something made me think of my own.
