I saw another thread kind of like this, but I think my question's different. Today at work, I had no cigarettes for the first time in quite a while, and I had horrible headaches, felt like puking, and my heart and lungs hurt. First off, I'm not sure these are normal withdrawal symptoms for nicotine, or if there's something else going on in addition. But my main question is, when my chest started hurting, I started kind of panicking, and I almost puked at my desk. I don't feel like I can even function any more, but I'm afraid to ask for help with task management or anything because my job isn't very secure, and I'm hurting financially. One of my supervisors asked if I needed to leave early, which I really wanted to, but I can't afford to take any time away. Is there anything you find helps when you've got to sit down all day at work? What do you tell people when they're concerned? The ones I like, I tell them I'm quitting, but I feel ashamed even then, I can't explain why.
