There are moments when you feel intense emotions for "yours". But at the same time you know everything is more temporary than the word "temporary" itself. It gives you pain the very next moment - the moment you realize it. Happens always to me.
There are two ways to deal with this. You can forget that it is maya and indulge in whatever you fancy. That doesn't stay for long though. But you can enjoy the moment.
People say there is nothing called "yours". They mean the carriers of soul. They look at physical things and tell you that nobody is your own. Maybe they are right.
I have a different point of view. I try to see things as God's creation. Maybe the material bodies are temporary but souls are their own, or rather God's children - human or anything else.
If you look at things that way, you are God's; that is God's belonging; I am God's child.
Thus, we are all connected... up to eternity because then you are looking from a different level. At that level, since everyone belongs to God, there is a strong bond among us all. We are all connected, via God.
These relations are permanent because the soul never dies.
In short, look beyond the physical. You will find everyone is your own. That is the concept of "Vasudhaiva Kutumbakam". That's to say that all creation is one big family.
