I am sorry you are in this situation and I know first hand the shock of it all. My straight forward advice is to review and study the homework from cadet, review and study DR and DB. The most important thing to remember is that you must make the changes for yourself. Bar none this is the most important thing to do. It is counter intuitive. You will struggle and even make mistakes, but you must stick to it and change for you. Focus also on being the best father on the planet for d7. The time with her will provide strength and moments of well needed joy. You will need that energy to get through the emotional and mental roller coaster. D7 will look to you and will know your love as you do this.
Post regularly here as there is much good advice, caring people going through what you are, and sincere genuine support.
It will be challenging but hang in there and you will come out better for it on the other side.
