Sad Ending

I used to make songs that were happy
when everything was sweet and lovely
Thought I could not write them gloomy
But reality happened to me

Stuck in this beautiful fantasy
Poured everything, it was leaking
Just the beginning,
there’ll be sad ending for me

But I’m not ready
I fear to leave here
I miss already
I wish I knew the ending
So I could stop overthinking now
I'm sure gonna be broken
I'm sure gonna be failing though I try my best
My little wish is just happy
I'm so blue
Da-le-la-le-la, le-de-la-ta
I used to forget how much I loved
When did I lose myself at first?
Can't control the sadness, it's too much
The reality is killing my heart
Did I take the wrong turn from the start?
Will I be able to live new life?
I wanna go home
I’m scared of sad ending for me
No, I’m not ready
I fear to leave here
I miss already
I wish I knew the ending
So I could stop overthinking now
I'm sure gonna be broken
I'm sure gonna be failing though I try my best
My little wish is just happy
I'm so blue
I do not know where I’m crying
Still hovering around empty space
I do not know why I’m crying
What is wrong with me?
