I have been DX with BPD for approx:15 years now. I never understood before. I am finally getting where I can see some of the things myself. My dear hubby has stuck with me some way some how.
I am not sure what one could do in my case as far as relationships go.
I see everything in black or white. Today you are either good or bad..there is no inbetween(grey)
I often find myself realizing I am constantly in turmoil within myself. I also think differently than others. I have a hard time understand that part. I feel what i feel just like anyone else does. yet I am told what I think is often distorted. I have a hard time understanding how so..after all we all have different views.
IMHO...I have to finally bust free some how before anyone can have a close relationship without my harming them emotionally. Not intentionally.
I cannot speak for your daughter..as I am not here nor do I know if she regonizes any of her symptoms. best of luck.
Hugs, Angie
