Looking after an orbiting rock

You have been on this piece of rock orbiting in space for a long, long time.

Your duty, since the first day, has been taking care of any of the dwellers that would require your help.

After several orbits, answers from the place you once called home became sparser and more and more concise. You've been cutoff from your colleagues.

After several more orbits, you realized some parts of you were starting to fail beyond care or replacement. You found a few workarounds, but something that was beyond your abilities was fixing your memory.

So you let it go. Things large and small you didn’t need anymore.

You have been keeping the precious space for information that’s relevant: your patients, their issues, their faces, their stories. Their families, their likes and dislikes.

After a number of orbits you haven’t kept track of, and letting go of more and more, you’re still here, on a rock, orbiting, caring. But you’re not sure for how long.
