that feeling when you feel that the right person is missing.

I do not lack attention in my life. I am always in the spotlight. a lot of people are near me. there are those that are very close to me. there are people whom I touch only once. there are just people. But only once in my life did I feel it was the NECESSARY person. and I remember how wonderful it was. I don’t even know how it happened that he died in my life. But next time I do not want to miss it.
it is that feeling when everything becomes a different color. everything becomes brighter and wants to breathe deeply. the meaning of life appears and you find such a person?
