~What is it?~

I have done
everything I need for today,
but have little zest for life.
What is it?

I can do
anything I need for today,
but have little energy for life.
What is it?

I have little interest
in a social life, but enjoy
my lonely life.
What is it?

When I come back to myself,
I notice time has passed
and I forget what I have done…

What is it?
Is it aging?
