A few questions, please, on the transmigration of souls aka "reincarnation"

What happens to our “less than perfect” characters as we journey from one lifetime to the next, if such a thing exists?

If our soul survives death, what does it look like?

Suppose someone recalls a person, or the persona, or mask that the soul inhabited—does that identity survive somewhere intact? Or is it thrown away, like single use plastic?

Someone please tell me, then, if we find we are missing someone, who, or what, are we missing? Was that ever truly them? Can they ever exist again, or do they exist in that version somewhere? Or are they gone forever?

In this world, all that’s left of our old home in Paradise, where we spent ten years, is a perimeter foundation and the cement front steps. I have so many pictures of it, taken while we lived there. Now the only place it exists is in those memories.

Is there a salvation army for the people we remember? Can we find them somewhere and pull them off a shelf and treasure them like they were never gone?

If we go to join them, which one of the many masks will they be wearing?

Who am I, really? Is there a better version of me waiting on some other side, longing for this act to be over? That would make two of us.

Do I exist at all? Sure feels like it. But will “I” exist after I’m dead and my body is ashes or compost? Will I need a suitcase, in which to carry all the previous disguises that my soul has masked itself in? Or am I going to be just some amorphous ball of energy roaming around with no recognizable physical appearance?

I’m hating my body because of its ailments, its lack of resilience and durability. But what if it’s all I’ve got? Will I ever again be the best version of this version of myself?

Please submit the answers in a timely fashion, because I’m losing hope, faith and patience. I’m hoping love exists, because this version of me isn’t upgraded with that feature. 

I'm hoping the next version of me isn't so obsessed with comma usage.
