Been pondering this further....
I am now wondering if maybe you are asking kind of.if you will ever get back to the normal that was before this happened? LIkely that is not what will happen. This has changed your life, it has affected you- if it didn't change your "normal" somethng would be quite not right.
So, somehow you now have to find some way you can go on.....with the new reality. The new normal. It can be very difficult to have to go forward when something so profound has occured in life, but..it has occured and it cannot be changed, so somehow you slowly find your own way to go on in spite of it. Some people find something related to a life changeing event and put efforts and energies into a new "cause" some people find ways to go on holding onto the idea that the person who is no longer here would be unhappy to find out the event stopped us from living our life. Some people become motivated by ideas for actions that honor the loved one who is now gone.
It takes time..... you have been shocked, traumatized, hurt. You have to have time to heal. Healing comes gradually, in bits and peices, with ups and downs. It comes in baby steps and small bites. In order to heal you have to take care of your needs, carefully. WHether you feel like it or not, you must eat well, eat healthy, drink water, eat fresh fruits, vegs etc....you must do your best to get sleep at your normal routine times, and you do have to be kind to yourself. While what has happened did not hit your body, physically such as a surgery might have, it still DOES affect your physical well being, and a good starting point in healing is to nurture your physical needs, as well as emotional. Tending to your bodies physical needs gives your emotions time to heal, too. It provides valuable resources your emotional self requires so it can begin to heal. Be patient with yourself. Do the small little healthy things that feel good for you, and build on them slowly. each baby step is one more step on your journey to healing. Sadly it does not come all at once, it does not come quickly. But each little baby step is a positive thing in and of itself. And some days you may find yourself just needing to hold ground just where you are, without a little baby step forward. Thats OK, too. There is no rule book, no law that says you must heal in x number of days and be done. It is a process..it is ongoing.
