Hello antony_james. A couple thoughts as alternative perspective.
i am now have been in NC for couple of weeks. Still i get the self doubts, guilt and shame (which i know are not real).
Self-doubts, guilt, and shame -- in my opinion -- are "real" in that these are emotions that reside within us. We can "hold" these emotions rather than "repress" or "express" -- but I think it's worth learning to identify, label, and work with emotions that arise within us.
I have an idea to contact her exbf through a fake fb account with a message asking if he knows someone who was close to him with BPD and i would suggest if he does not know what is this disorder then he should check it out and get back to me. I really want to talk to this guy to reassure myself that it is not me. is this a good idea or will it shift the situation to chaos ?
You asked for comment, and here's my opinion:
not a good idea.
We all wrestle with the end of our relationships. We all have self-doubt.
Why triangulate with a third person? It makes us play "victim" when, perhaps, it would be more helpful to work with our emotions. The sooner we look for answers WITHIN ourselves, the sooner we begin healing. Period. That's my opinion.
