Hey Linda, hopefully by now you're feeling a little better and these fine folks were able to help you realize what you are going through is completely normal. Don't worry about biting anyone's head off, unless you do it literally, then you might have to worry lol. But seriously some of us in our early quits got angry some of us cried over spilt milk. It's totally normal.
One thing that really helped me in my first months was my JAC, jillars air cigarette, I just pretended I was holding an actual cigarette in my fingers and then went through the motions of "smoking" it. I might have looked stupid doing it but it really worked in tricking my mind into thinking it was getting its fix. Some members have used cut straws, pens, etc. Maybe you can give that a try?
About your profile pic and ticker, I think a moderator can help you with that.
You're doing great Linda, be super proud of yourself!
