I have the same thing @L-L, I switch between anger and serene calmness. I'm angry when I think about myself, I'm angry at my partner, I'm angry at work, simply because I'm me, because I still am, and often times because I have moments of hope left, which make me feel shame and resentment towards myself.
The other option is I'm completely at peace, resolved and I know what will happen and when it will happen.
I think the switching for me is the battle between the heart (that hopeful bastard!) and my brain (which has analyzed the situation logically and has determined that there is no other way which doesn't lead to suffering).
I am very much rooting for my brain.
