Truly Unexplainable

I sat at lunch today,
I didn't even know what to say.
It felt like the blinds to my mind
Had been shut all the way.
It was the strangest thing,
Something that would help me bring
Beautiful words for a poem,
I sat there,
Quietly thinking up lyrics in my mind.
What was wrong with me?
I don't know,
The answer to that question I can't find.
It was so uncalled for,
I don't know why I was suddenly so upset.
Everything was fine,
But randomly I started losing it.
For a couple minutes I wanted to burst into tears,
For a couple minutes I wanted to smile and laugh and I felt cheer.
For a couple minutes, I just sat there,
Thinking nothing at all.
But I can't explain it,
I was so confused
I thought I was going to fall.
What the hell is wrong with me?
I just realized this today,
My feelings are on a roller coaster,
Never the same,
What should I do?
Am I to blame?
So I decided to come running home,
And just simply
Write about,
Relieve my worries in a poem.
