From what I gather, you were a non smoker who started vaping in order to self-medicate some sort of depression or something? Could be wrong, as this thread has been hard to follow lol. I wouldn't recommend getting addicted to nicotine, be it through vaping or cigarettes, and ESPECIALLY not cigarettes. Nicotine does indeed flood dopamine receptors, and takes control of their production so to speak. This is why cig smokers need one in the morning, and can't last many hours without one. The nicotine manipulates dopamine output to the extent that the human body recognizes nicotine at the importance levels of food and water, thus giving off a small "reward" (dopamine) for in ingestion of nicotine (as the body naturally does with food and water).
Putting your body through essentially a foreign invasion just to try to better your mood (which in the long run will deteriorate your mood stability) isn't a good idea imo. Try improving your diet, socializing with friends/family, picking up an instrument, exercising, and practicing meditation. I find that naturally improving one's life almost always equates to more energy throughout the day and more stable feelings of well-being. Willingly becoming addicting to any substance is never a good idea. Hope this helps.
