Replaceable/Irreplaceable

Are you forgetting someone?
Someone who stood by you.
Cried with you.
Dropped anything for you.
Are you forgetting us?
All the music.
All the laughter.
All the special times.
Are you forgetting our friendship?

I went through a lot with my friend and now I feel completely replaced. Juvenile, but I mean... it hurts.
