You don't have to start all over again.  You were strong 4 weeks, THAT'S AWESOME!!!  Focus on the four weeks, not the ONE time you gave in.  Don't loose those four weeks, celebrate them! You deserve it.  Learn what you can from the one mess up and move on.

Lost ~ You're not "this person" anymore.  You made it for four weeks!  That's better than when you started.  keep going, you'll be fine.  Being angry or upset about a slip up shows your heart and your mind is is in the right place.  Just get your impulses on board!!

My dear friend, I know your frustration. You want it over with right now and feel that your life is not your own because of this "stuff". This is not something that goes away "all of a sudden", but don't worry. You are living the miracle of the Gospell. We all try to live up to our own expectations of ourself, as Lloyd stated, and fall short.

You know all this stuff.

Just want you to know that you have friends that care about you and are with you. It'll work out, though I know it doesn't feel that way now.

I don't know what you gave into, nor is it my business; however, I feel compelled to ask you what we can do to help you. I think most honest people will tell you, we have all failed to come up to our own expectations.  I think most of us will tell you we have struggled immensely to over come our mortal  or natural man (woman) inclinations.  Don't give up. I struggled for 30 years with many issues, but have managed to overcome most of them. (cussing is my worst now: finally) But I did find I could not over come any of them without first, the scriptures, second prayer, third support from family, friends and acquantinances, and fourth a belief in myself.  I had to learn to like me, let alone love me, and I had to learn to forgive myself. So, realizing we are worlds apart, held close only by this machine, let us help you. Tell us what you need.  I promise I'll do everything I can to help you.
