I'm 17 And I Have Been Smoking Cigarettes For The

I'm 17 and I have been smoking cigarettes for the past few days. It's the first time I've ever smoked, and don't plan on doing it again as it was a horrible experience afterwards. My chest hurts, I feel kind of nauseous, my chest (breathing wise) is tighter, I have lost the will to workout, and I feel irritable.
If I stopped smoking will I feel normal again?
