I'm so sorry for this devastating loss!
Don't feel badly that you're having trouble processing all of this right away, or at all. The whole thing is a huge shock to your system that's just too complex for simple answers and quick fixes.
For me, time itself has been a huge help. Having landmarks in time so that I could say "It's been a week, a month, six months, a year, two years ..." really helped me realize how much things had changed for the better in terms of how I felt and how I responded.
Be sure to reach out and talk to others. Pay attention to the offers for help and a sympathetic ear. Realize that not everyone who makes the offer will follow through in ways that you find comforting or satisfying, but that if you just keep reaching out, eventually you'll find some people who can truly offer the soul-healing sort of connection that seems to bring some light to the darkest days. Don't close yourself off and hibernate. Don't reject the idea of help and solace, you're just delaying the inevitable.
For a long time after my father's death, I was inconsolable. I was 'doing everything right' but needed time to heal from the physical and emotional exhaustion.
No timetable that already exists will serve to tell you exactly when your sense of normality will stabilize.
It sounds to me as though you're on the right track.
Just hug the people close to you and take care of each other.
You have my sympathies.
