I'm with sierra, MKAC, and feral as well. This is just a bump in the road. Try to let it be what it is and no more.

When we are trying to change our thoughts/behaviors it takes time, and we all fall off the wagon so to speak.

The key is just to get right back on it and keep it in perspective.

You'll be alright. These things happen and they just really don't have to be that big of a deal.
