Insomia?

I went swimming with Jing and co. in the noon.
Then we went basketball at SKCC.
After that i meet up with Yang and co. at plaza.
I had a eventful day and
Im very very tired now.

I want to sleep yet i cant fall into my dreamland.
I just cant bear to sleep.
I flipped up, down, left, right to relax,
To find my comfort spot but
Countless ramdom thoughts in my mind keeping me awake.
Is this insomia?

How i wish im able to fall asleep easily. :)
