I think that many of us probably had/have those thoughts or something similar.
We all tend to believe that our situations are different from the next person's. But reading the stories of the people on this forum tells a completely different story. There are far too many similarities. It's scary in a sense. It's almost like there is a script that is being followed.
With regard to the second to last one:
"I'll never find this kind of connection ever again."
You should probably be happy about that one. The type of connection that we have with our pwBPD is not something that any of us should actually want. It was damaging. It was unhealthy. It was unsustainable. It was, in some ways, about control and being controlled.
We should want a pure, healthy, loving, non-damaging, and sustainable connection with another person that does not center around control, but rather compromise.
These types of thoughts, and their corresponding actions, can tell us a great deal about ourselves if stop and take the time to listen to them and examine the true meaning behind them.
