First Thing's First
Try not to let your mind go to the "How can I do X without alcohol for X amount of time"....that will come with time (as I'm told!).
First thing first, you need to get some medical help. I understand about the lack of insurance but you should be able to call a hospital in your area, explain your situation, and they'll either help you there or direct you to a facility that will.
I know it's scary but I promise you that, with each step, it feels like another weight has been lifted.
Good luck, my friend, and know we're with you!
