Very very much so.
My D9 summed this up rather well when we were discussing in the car the other day with D7.
Enabler - Am I good at taking responsibility for when I do things wrong... .mess up... .you know?
D9 / 7 - Yes Daddy, you're very good at that
Enabler - How good are you at taking responsibility for your mistakes?
D9 - Ohhhh not very good, like yesterday when I got out the bath and whacked my toe on the toilet, I was so angry I blamed D7... .
All - chuckle chuckle
Enabler - that's perfectly normal D9, often when we feel bad things we don't like to take responsibility for it and we blame other people. It's not a good thing to do and it's far far better if we take responsibility for the mistakes we make. Just because we do 'a thing' wrong does mean we're bad or wrong.
D9 - Mummy is really really bad at that. She shouts at us every day that we're not ready for school, but it's because it takes her so long to get ready, we're always late for school... .don't tell mummy I told you that will you... .
A person suffering core shame
https://bpdfamily.com/content/shame-powerful-painful-and-potentially-dangerous-emotion for an extended period of time will develop defense mechanisms to protect themselves from the bad feelings of shame. To the point where they may not even acknowledge their own mistakes and instead make up an alternative fantasy which changes their reality to the point where they are no longer "wrong". In much the same way that D9 blamed D7 for her stubbed toe even though D7 was nowhere to be seen to avoid the feeling that she had kicked the toilet in her OWN stupidity, adults may well invent very elaborate stories (which they believe) to explain away events in a manner such that they suffer no feelings of shame. e.g.
"I'm so busy all the time running around after the kids and doing stuff around the house, I'm always busy doing things for other people" ... .you went for a 2hr run this morning and spent 2.25hrs on the phone to your lover, no wonder you have run out of time to do anything today. The little lies we all tell ourselves (but consciously know the truth) are exaggerated by pwBPD to the point where they believe the lies and live as though they are true... ."I am abused", "You are controlling", "You're threatening", "You abuse the kids", "You're a coercive controller"... .It can get pretty extreme and gets worse and worse the bigger the cause of the shame is.
