Your story reminds me of my own. My dad died recently from COPD, you will get that from smoking. So all stressed out what I di lit cigg that I had from a friend. Hugh mistake my brother just happened to be driving on my street at ht hour and caught me figures!!! From that point I just stopped. I thought about what was most important in my life and how I wanted my future to play out, honestly I didn't want to die like my dad from a smoking related illness. I would chew gum, cinimmon sticks, ect to kill the craving and even to this day it's hard for me, but I wan to live a long healthy life, not a short sick one. So try to balance what you wan or u, and tell ur bf to show some kindness to u, I'm sure he does things you don like. Love yourself enough to give it up, remember you are worth it!!!
It is an unfortunate answer, and one I am sure you are sick of hearing, but there is only one way to quit. With the desire, and conviction to do so. No one can do it for you, and no drug can do it for you. There are some drugs that can aid in the process, but from what I have read they are often ineffective, and sometimes have very undesirable symptoms of their own.
You will never quit without wanting to. That means wanting to badly enough to suffer through the anxiety, and depression you will have during the next few months without smoking. You will also feel a strong desire for a cigarette when watching someone else smoke. This effect can last for several years after your last cigarette.
I do not know you, or your boyfriend, so I may be way off by saying this, but I am concerned with the way you have briefly described your relationship. It sounds like he is more concerned with controlling your actions, than helping with your health. Helping you to quit would be a good thing, but no one should be forcing anyone to do anything in a relationship. It sounds like he doesn't even have any interest in talking to you about your problem, but rather making you live the way that he would prefer.
I do have similar experiences, unfortunately where I played the part of the boyfriend. In high school, my girlfriend at the time could have posted your same exact story to a t. After a few years of maturing, I can now see what a ***** I was being, and hypocrite, as I occasionally smoked without her knowing. It has long since occurred to me that I really didn't care about her smoking, but that she had continued to do something that I didn't want her to.
After writing all of this, I noticed your post is from November. I hope my answer is still helpful.
