Sleep is a pretty vital process with a lot of health implications for the brain and for your body. Reading Ariana Huffington's book "The Sleep Revolution" was pretty eye-opening, also see this article: https://www.theatlantic.com/health/archive/2014/07/arianna-huffingtons-tips-for-better-sleep/373884/ https://www.theatlantic.com/health/archive/2014/07/arianna-h... Sleep helps your body regulate stress including mood. The lack of sleep can be attributed to your procrastination, as well as other possible health issues such as a lack of focus and lack of self-discipline. You're not at your optimum best. In addition, I noticed avoiding caffeine (or going decaf) is pretty helpful. Too much caffeine reduces the quality of sleep. I personally noticed sleeping upwards up to 8 hours and feeling like I only slept 3 hours -- because my body was over-caffeinated. Cutting-down caffeine (or going cold turkey) helps a lot in the quality of sleep. For focus -- meditation will help greatly. Learning how to meditate and doing it daily even for 10 minutes will train/discipline your mind.
