You need to ask yourself: Is this how I will continue to deal with frustration? By putting goodies in my mouth? And where has this gotten me so far?
So you need to realize that everybody gets stuck. I'm stuck right now. But YOU GET UNSTUCK if you stick with it.
You also should find something else to do, say, or dance on when you are frustrated. You gave up your old way of dealing with frustration by embarking on LCing. So you have to find a new one, don't you? That's a good goal to have right now.
After all, you started a new way because the old way DIDN"T WORK. So, you can't go back to the old way, when you know it doesn't work.
I know you can think of a better way.
