Go to an alanon meeting in your area. Trust me it will help and it's a form of GAL.
Your w is clearly going through some heavy stuff right now and unfortunately it will take longer then you would like for her to come to her sense. Changing your time frame for her possible recovery will help you tremendously.
Being a single parent like I am right now is hard. Ask for help. If can afford to hire someone to help around the house, or maybe asking family for a hand is an option. This is a crisis and you can't get through it alone.
And seriously alanon works
