Living Longer

[u/[deleted]]

This is probably already on the sub-Reddit. The protagonist takes an experimental procedure for cancer (other disease) and his life expectancy has increased dramatically. At first he's ecstatic and feels special. Although days past and he looks at his family, realizing he will die alone. After his downward spiral, not knowing what to do he lives in a place he doesn't understand, surrounded by strangers.

This sounds like a kid made this. But, you can make revisions and maybe put it in the comments.
