Linzey, the best way to move forward is to not look back and to set new and wonderful goals for yourself.
Distract yourself with healthy activities, take courses or find yourself some Al-anon meetings and learn to make healthy choices in life. Find a new hobby, plan a trip...it doesn't have to be expensive...even a bus trip to visit old friends or family, or to spend a weekend in a pretty sea-side town will bring you fresh air and a good attitude.
Mostly, just focus on healing and your own well being. Don't linger in dark thoughts of the past, toss out anger, sadness and resentments, they will never serve you well.
It takes time and it takes work, but you are worth the effort and I promise you that you can and will have better days ahead, if you set your mind to it.
You've already made the decision to move foreward, that's the biggest step of all.
