SWCH- whatever it takes..
I have made some genuine friendships in AA. For months all I got out of it was coffee and biscuits- and human company.
One day at a time? For me it seemed second by minute by hour some days. Post here a lot- join the threads- get involved.
Listen to your body and doc about the health stuff. I was dead 3 times in rather awesomely horrible circumstance- but the cards on the table told me if I did not burn, it would have been the liver, or a bus, or falling down stairs....
Support and my prayers.
