Hi Blaise
in my personal experience anger and sadness are nearby.
Perhaps you shifted your anger to BPD. Are you generally a bit low in your energy right now? For me it is more difficult to feel anger when I am low in my energy.
These 5 stages are not the same for everyone. I would not worry to much about it. Stick with feelings and thoughts that are there.
I still cannot figure out why I cannot divorce from my wife.
Good question!
