Is this me?

Lost
The feeling of hopelessness
Of not knowing where you are
What you are
Who you are
When things that used to make you happy
Bring you joy, make you, you
Just aren't the same
You know you like them-
But when you think of doing them
It makes you tired
The feelings you had before of excitement
Have all but vanished
Except for a few moments that
Give you just enough hope to keep thinking
Yes
This is me
But is it really?
