i am so sorry that this happened to you. I hope you can now heal and fnd the help and support you deserve.
I believe that we are all individuals and will grieve and heal in our own way, in our own time. So allow yourself as much time as you need and allow yourself to do what feels natural to you.
If you feel up to this, I hope you will consider reporting the incident, as this information may help someone in the future.
All the best.
