Another One Lost

Losing friends is tough
But I'm strong.
I will go into this battle
And emerge victorious.
No one knows how I feel
So all the more glorious.
It's sad being alone
But that's now all I know.
The days pass slowly
And it's a continuous spiral.
I put on a happy face
But inside I'm the opposite.
I'll hide this till the day I die
But I think you've won.
