How tough is life ?

Well this is an exploratory post, not having high expectations that grapevine would fix it for me. But to put it in short, I literally have no family, everyone i had now are gone. Friends, yes , quite a lot, but they have/will have a life beyond me. But none when it comes to family.

Here to just understand if someone is living all alone with no parents/siblings/wife/kids/partners and how is life ?
