I have seen families, once destroyed by addiction, become reunited with love and forgiveness once the change becomes trusted. They are perhaps better off than if the harm had never been done. The rebirth gives meaning to the rejections of the past. The awful past becomes their greatest asset.
Do not give up hope nor be afraid to come back and make amends for harm done. You have nothing to lose but pride. Losing pride is freeing.
Peace and Love,
