You should join our club. Posting, reading and spending time on the site is a good way to distract from anxiety and such.
How do I join?
The short answer is post roll in the May quitters group. Posting roll means you promise to quit for the day. one day. The next step is keep your promise. Wake up repeat.
For more detail, read some of the info that scowick pointed you to. I have to run, but I'll check back soon so let me know if you have questions, or feel free to send me a PM.
