There is no right or wrong way to go through the grief process and it is different for everyone as well. Some feel the grief immediately and others feel it after a few months...no way to predict how it goes. You say that you have gone through it all and without a lot of pain and I don't doubt that, but there isn't a perfect box of grief to say you have moved through the process. Sometimes we have a delayed response to the deep pain. Time will tell if that is the case for you but however it goes for you, I would suggest that whatever feelings come up and in whatever time they do, that you continue to feel it all and talk about it all as that helps moving through this painful process. Sometimes we take steps forward and then a few back and that is okay and all normal. The reality of it all may not have set in fully or maybe it has....take each day as it comes and feel whatever it is that you do feel.
Let me know how I can support you further.
