The aggression sounds like a normal reaction. I'm very sorry you're suffering.

I've had periods where I was endlessly and rapidly moving from pain to anger to denial.

Then back to pain.

Pain is the worst of all, isn't it?

Moving into anger was the only way out of it.

(The anger couldn't be sustained for long, as it took a lot of energy. I'd go into denial again... )

I don't know if that's similar to your experiences?
