It's not a phase, just depression

I...

I was happy.
I had you.
You made me happy.
You made me smile.
You made me laugh.
You made me cry.
You made me fall in love with you.
I couldn't wish for more,
But then,
I know it won't last.
As much as I want it to last forever and ever after.
Eventually  you'll leave me,
Eventually you'll get tired of me.
Eventually you'll find someone better,
someone you deserve,
But I'll be here.
Still waiting for someone to fix my half broken heart.
