Nope, you're not alone. Your quit is still very young and the adjustment process is still ongoing. As smokers, cigarettes are tied to most every facet of our lives. When we quit, we have to learn to do things without the cigarette that served as our little crutch for so long. You combine addiction and mental conditioning that is carried out 20+ times daily, and it is quite natural to feel off at times during the initial days of a quit.
Your emotional state will not only calm, but you will have the added benefit of not being in varying states of withdrawal for the rest of your life now that you have quit. The only thing a cigarette offers is a temporary relief of nicotine withdrawal. And the only reason we ever felt nicotine withdrawal is because we smoked. You've eliminated the source of the problem (cigarettes) and eventually the problem (withdrawal) will be a thing of the past.
You are doing exactly what you need to be doing and soon it will become very clear that everything encountered in these early days was worth it.
