You're still in the early days of your quit Linda! I know it seems like it's been forever since you had your last smoke but it's hasn't been that long actually. Part of the early process is time distortion that makes each day drag on endlessly. Seemed to me those days were filled with misery but you can control that somewhat by focusing on the positive things you are starting to see. Sure, there will be some days when you feel you have taken a step backward. That's how the process works .... very slowly.
Give your quit 6 weeks then tell us if we were all wrong about things getting easier or not. We were all like you. I was still pulling my hair out at times during my first month but those days just kept getting fewer and fewer throughout the first month or so. There's no specific time frame or switch, like a light switch, when suddenly we feel OK with our quit. It's such a gradual process you will not even realize it's happening. It just does, on it's own as long as you don't give in to your junkie thinking and light up a smoke (NOPE) You can also help that process along by focusing your mind on the positives you notice rather than the roadblocks your junkie brain, or what's left of it, tries to have you focus on. Positive attitude makes a huge difference.
The other thing you can start doing is take another look at what smoking really does to people. We tend to ignore all that stuff when we smoke because we just don't wanna know! Look up articles on diseases such as Lung Cancer, Buerger's Disease, COPD, Emphysema, Heart Disease. You will have a new perspective on things now and be much more willing to accept the truth about what smoking really does to us - it's NOT our friend! Kick your nicotine addiction in the A*s and out of your life forever!!!
