Tzadikel,
The Y"H has plenty of tricks.  You recognized this email thing for exactly what is was, and that is HUGE progress.  You were aware of the rapid downward spiral a slip has the potential to lead to.  You did some great thinking!  Don't be so hard on yourself.  A p*rn and lust freak isn't the real anyone!  You have a neshama, you are a neshama.  Don't ever forget it.

Make sure to fill your time constructively. Maybe including posting chizuk on other people's threads, maybe a new learning seder or shiur, exercise.

You have come a long way in a short time.  There's no need to fall.  Stay the new you!  It's the real you.  One day at a time.  One nisayon at a time.

Have a wonderful Shabbos!
Alex

I don't have any sage advice, but I can tell you a story.  hey, everyone loves a story.  I grew up modern orthodox.  I went to learn in Israel after high-school and became much frummer.  Before I left, I asked my sister to record some TV shows that I didn't want to miss.  She faithfully recorded them for a full year.  When I got home from Israel after a year, she excitedly told me that not only had she recorded them all, but that night, both shows were having their season finale.  One for the season, and one was the last show ever. 3 hours of "can't miss" TV.  I felt really bad telling her that I don't watch TV any more, but that's exactly what I did.  It's hard to break old ties. You can do it!

Gibbor brings up a very important point.  All this stuff is only "must see, must do" when it comes up.  If we let it go by, go to bed without it, by the next day (or the one after) it's nothing to us.  It's like this with every impulse.

Ask yourself: In one week from now, will I regret not looking at this, watching this, doing this?
