Congratulations on 13 days and welcome to EX. I think the best thing to do is to accept that the craves are going to come no matter what...they are really intense in the beginning but they DO get weaker and less frequent the more time you have behind you. I suggest that you acknowledge the crave...figure out why you are having it and then ask yourself what having a cigarette would do to change whatever is happening. The only thing a cigarette will do is to take away the crave for a very short time and then the nicotine level drops and you want ANOTHER cigarette. That's how it works and in the meantime...nothing has changed, cigarettes do not relieve stress, they actually feed it, cigarettes do not help with depression or sadness, they make us feel more isolated and increase our depression, they do not help with physical pain, they distract us for a very short time and there are much healthier distractions...see Jennifer's comment to you. They do not help with anger...I remember smoking FURIOUSLY when I was angry...I would visualize the person or thing I was angry about incinerating. Clearly, that did not happen. I always felt angrier and angrier, I actually had arguments in my head..you know the I should have said, should have done things? Smoking does nothing FOR us but I can tell you that it sure can do a lot TO us. No crave ever killed anyone...no one can say that about smoking. I suggest that you do all of the reading about nicotine addiction...read blogs here, comment, write blogs like you just did...ask for help if you feel that your quit is at risk. Write a blog and put the word HELP in the subject, we will do everything we can to help you to get past the trigger. I used the mantra NOPE all the time at the beginning of my quit...Not One Puff Ever. It was simple, easy for me to remember, and it helped me to keep my commitment to myself. You CAN do this and there are lots of people here who will help you and who will hold your hand when you need it, we ALL want you to succeed and to be an active member of this community. I am adding a couple of links here for you, one is a blog written by SkyGirl and it is really helpful.../blogs/SkyGirl-blog/2017/10/29/here-s-what-smoking-doesn-t-do-for-you The next was written by JonesCarpeDiem and I read it over and over again when I first quit.../blogs/jonescarp.aka.dale.Jan_2007-blog/2011/06/26/what-to-expect-in-the-first-four-months This should give you a good start.
Again, welcome to EX and please let us know if we can help in any other ways.

I was able to beat back my worst cravings with "Box Breathing."
