I can't afford to lose one friend

Never thought we'd ever end.
I can't afford to lose more friends.
Not to have you close at hand
Wasn't quite what I had planned.
(It's that time)
Is it that time?
A moment that will pass
(Yes, it's that time)
Is it that time?
We knew it couldn't last.

I'm just trying to catch my breath.
A heart that beats itself to death,
Panic stricken by the thought
You're not here for my support.
(But its that time)
Is it that time?
A curtain has to fall.
(Yes, it's that time)
Is it that time?
The writing's on the wall.
(You're in your prime )
You're in your prime now, darling,
And that's the worst of all.
It's just that time.
Night must fall.
I'm so lonely.
I'm so sorry.
