I will give you one tip OIN. Your wife feeds off your hope. If you feel hopeless she has nothing to live off of.
You need to project hope when around her. I know you likely do. I just thought I would mention it.
I honestly do think you are doing well OIN. If you compare your wife now from a long time ago when she was at her worst I think you will see considerable progress. And yes you can give yourself credit for that.
