Welcome Screw Grizz. Great decision to quit and congrats on 8 days.
My recommendation is to forget about the shame guilt you feel. You can't do nothing about the past. What is done is done. You found the light brother.... KTC.
Similar concept is how we quit. ODAAT. We wake up, post roll and quit for today only. We don't worry about the future whether it be 1 day, 1 week, 1 year... Because we don't control the future. We control our actions today. We control whether or not we throw poison in our lip today. And we just flat out don't do it -- we keep our word and we stay quit.
You can do this. Keep fighting today. I'm quit with you all day long.
