Bad Day

I am not sure exactly what is the cause for it but today I seem to be in a funk. My mood is really just blah and every little thing is getting on my nerves. It is like the smallest thing in my mind is completely blown out of proportion. I cannot blame it on the weather because today it was sunny and in the 70s. Absolutely perfect. Tomorrow on the other hand it is supposed to be cold and raining. I just hope whatever has me down goes away when I wake up in the morning and does not carry over to tomorrow.
