PS -- Your Nmama likes drama. And death is a drama.
It doesn't mean she didn't love him at all.
But if she's an N, her love when she can tune into it, is a blunted thing.
Remember that she has a mental illness that means where you might
expect softness, realizations, piercing loss, sorrow...you may see a
lot of weird off-tone, chaotic or confusing reactions instead.
Remember that this is her mental illness and personality disorder.
It is very sad but has nothing to do with your own grief, which
you are entitled to feel in your own way.
I am so sorry you lost your brother, and so tragically.
I would be very glad to hear a story about him -- good things
you remember or feel, as well as the bad.
I won't be able to feel grief when my brother dies, I believe.
Your brother is lucky that you are remembering him with some love.
hugs
