Please help, I just can't stop thinking about quantum immortality.

What if every person reading this right now is occupying their own universe and as we age the bonds between our physical self as perceived by others and our conscious self from which we perceive the world weakens, thus meaning that when we age our physical selves will die and other people perceiving them will witness them dying from their own universe, but our conscious self will just go on living forever making every single one of us a medical anomaly?

So we have two physical forms, the one which other people see and the one that sees other people. You cannot see the version of you that everybody else sees and likewise they will never see the world through your eyes. I don't want to be a medical anomaly guys, why would I want to live forever as a fat loser?
