This is the way I was last week! Guess what? I got over it. You know what I did? I worked out HARD. I FORCED my grumpy ass to do that. 8 miles later, I was my old self again. I guess I released some much needed endorphins and got all my "funk" out via physical activity. Want to give it a go?
If you don't have anything nice to say, don't say anything at all. =)
