I've had a relatively mild case of insomnia over the last few days. I have not gotten enough sleep and it's starting to catch up with me in the form of yawns, headaches, sleepiness, an inability to process thoughts the way I'd like to, and more outwardly - crankiness. Being cranky is one of those things that will creep up on you when you least expect it; you think you're fine, and then you come out with some sort of unkind word or action totally outside of your normal character boundaries.
With the Holy Spirit in my heart, the cranky part of me that I've been battling for the last 48 hours or so is easier to reign in. I thank God for His grace and His love and His word... without them, this bought of lousy sleep patterns would be that much more unbearable: for me and everyone else.
