Is it normal for me to be this angry over this?

You may have some angry issues.
I think it would be good idea to seek some therapy.
Not trying to be mean or anything.

Or it could just be some hormones
and a lot of held back rage.
Sometimes people can just snap
and have to let out all the rage.

It's good you didn't let it out on a person,
but too bad for your fan.

What's interesting is that
something like this also happened to me.
I was having a stressful time in my life
and I just got so mad that I kicked my fan.
Luckily I did not break it, but still.

I've learned to control my anger a bit better
since I've grown and matured.
