"Jason, welcome to the site. And Hurrah!! You have gone 6 weeks or more! Well done.
Then you got "bit." I blogged about a similar experience to yours here:
http://www.ldsar.org/ViewBlog.aspx?EntryId=5704 If I understand your concern, you are very afraid of "starting over." Can I ask why that is? You made it six weeks without anything questionable. Why do you fear starting from day 1? You can go another 6 weeks or more. You start over every day...every week...every month...every year. Why shouldn't you start over now?
Your fear of starting over reminds me of the reason that I asked the question "Who's Counting?"
http://www.ldsar.org/ViewBlog.aspx?EntryId=5745 When Heavenly Father asks you to report on your life, I'm not sure he'll ask how many days you've been clean. I think he'll be more interested in your current state of mind. Are you humble, repentant, faithful, and charitable? Those are my questions to you. And I think Alma asked similar questions in Alma 5.
Anyway, congratulations on 6 weeks. I am truly happy for you, and this is a time to rejoice, not to sorrow in your possible sin. Start over, if you must, without fear. Recommit to put God first in your life--not just today after you faltered, but recommit every day!
With love!"
