Health risks and horror

Hi!
I am 20 years old female, had been smoking for 3 and a half years now. I had root canal procedure around age 14. Last year, that same tooth gave me trouble, it gave me a cyst (dental apsces), I lost my tooth and continued with my life still smoking...

Ten days ago, it all started again. I had another cyst, same place, stuck in my jaw. I lost another tooth and had an inflamed cyst and incision of it that lasted for 3 days. I had a sterile gauze stuffed inside that incision and during that time and it had to be changed without anesthetic. I don't want to feel a pain like that ever again. Of course, I had to turn to the internet for more information and I read horrible things.

Fear filled my body and I felt sharp pain as I entered a stage of sudden depression and anxiety attacks that I though I left in the past. My dentist told me I had to go to maxillofacial surgeon and do some tests to check if it's something serious, I froze, he thought it's spread through my jaw. I went there, I had been told that I'm in the wrong place and they sent me to the oral surgeon and told me that they need to get to my cyst with surgical procedure and clean it, however, when I went to the Oral surgeon. they told me that I just need to finish my therapy and that the cyst was gone as soon as it had contact with air. 

So, my friends, fear already did its job, I stoped smoking and the only time I think about it is when I thank the universe I stopped (And when I drink coffee haha). Wish you all the best of luck, that motivation you need exists somewhere, you just need to find it, don't lose hope but remember that clock is ticking. (English is my second language - if anything's unclear)
