There is nothing you can do for yourself, except giving yourself the time and space.
There is no magic potion for it, it just takes time.
Just know there are always others who also have to cope with the same loss in their own complex ways. Some people cope by changing their memory and describe the characteristics of a person completely differently, alienating your experience. Nobody will correct them, because everybody becomes so respectful towards others. Without real notice this damages relationships in the long run. It shouldn't, but at some point you can't stand the people close to you and their sadness and twisted polished stories anymore.
There is no malice to it, we all experience things differently. Do you ever really know a person? A whole life is quite a long time and some of us only see some facet of the life of others and there are things we don't want to see.
It seems strange, but the dead really don't care about this world anymore, it is only for the living. It is not about respecting their whishes, it never was, the dead are owned by the people close to them and they even decide who that person was. It is about what they need and that is the unimportant stuff you should forget anyways.
Many great mathematicians are buried with citations, they already regretted when they were alive.
But after a few years and without the haze of pain and emotions, real human and normal stories and memories can emerge again. If you lucky, somebody is there who can acknowledge them with a smile and a mind falling back in time. That is the good stuff.
May your experiences be different.
Your time machine is between your ears, it is very powerful and can be tainted by emotions and pain, so be careful when to use it out loud.
The Marshall Islands, which accept Taiwans to be a sovereign nation?
Most of the EU, the USA and Russia do not officially state Taiwan is a sovereign nation to not antagonize China.
Yet if China wants to host the next world war, a lot of nations think they are well prepared for the occasion.
None of us can do anything about it.
