Is it normal to write breakup poetry?

When I was with you the moon was so bright
The wind through the trees was a beautiful sight
Now you are gone with no hint of return
I care not for the world, I'd watch it all burn
Between Summer and Winter I stand on the line
Can I crawl back or is darkness all mine?
Waiting a while with my tears almost dry
I smile deranged and let out a loud cry
I cannot imagine these feelings will end
There's no point its over, I will never mend.

Damn.. I need to go watch a boxing match to get my masculinity back.
