Honestly, I would put sleep above a shrink - especially since finding a shrink that truly works well for you is often quite the challenge. You can figure out many of your own problems, but not if your brain isn't getting the full recharge it needs - you simply cannot replace lost sleep. One bad night of sleep takes several consecutive decent ones to make up for, and I've seen some experts say the damage to your brain from lost sleep can never truly be made up for, with the negative effects accumulating over time.
