Follow Sandi's advice Faith. You're strong enough to do it. Every hour/day of going dark you'll grow stronger.
I wouldn't think of doing it any other way. I have followed Sandi's posts as much as Robx, together they are "Rock" solid from there perspectives.
Now as far as dropping the rope mentally, it's a battle. I swear there is a new memory of the deceipt popping in my head every 1-2 hours. I'll just be doing something at work and then BAM another revelation. It's horrible and it makes me mad, but it's all part of the process.
Sandi was right about the word she used...WRATH. It's pure Wrath. I don't hate my W, but I'm extremely disappointed and it does swing back and forth between wrath and pity
