We've all been there. But not all of us have always known how to navigate in other directions as soon as we should have, understanding that this bond, fulfilled its purpose and was only untied, to leave us free, but not adrift, but with a long way to go.
There is a "universal" law that says that the void will always be filled.
If only we could turn that feeling of loss into one of motivation, of joy... because life is giving us new possibilities in the infinite field of possibilities.
It's often difficult to see the way forward when caught up in the effects and feelings of loss. Grief after a death can be all-encompassing and even when one has lost a friend one can be left in a state of aimlessness and unable to see perspective. As you say though, we must as there's always a path forward and new possibilities ahead.
Losing a friend or family member because they die is a terrible thing and it is a wound that needs to heal in some way. I am so sorry for your loss, G. For a moment I thought you were talking about a person who moved away from you, but not because of death.
Anyway, sometimes I think that if someone close to us dies, the least he or she would want is to see us trapped in suffering. This is a tough and complicated subject.
