I'm so sorry for your loss. What a terrible experience. While using alcohol to cope is not a great method, I understand completely, just as I understand your need to move on now, leave alcohol behind and be a parent to your daughter.
Alcohol is one of the only substances that can be fatal during withdrawal. If you have VA coverage, you should be able to get to a VA Emergency room and get help without spending an arm and a leg. There are some medications that can really help you feel more comfortable during this time. Still, no matter what you take, you're going to feel lousy for awhile. It took me about a week before I started feeling okay, but soon after I started feeling great! Good luck, and I hope you feel better soon.
