Mike, you certainly have been challenged in many ways. I am so sorry to hear of your job loss on top of your wife's physical condition. It indeed is terrible timing when you're trying to get yourself together and have a new life. My sympathies for all that you're going through right now.
I will state the obvious - nothing is made better by drinking. I know I don't need to tell you this - getting numb is just a quick fix. All your problems would still be there in the morning - along with another one - you would have let yourself down by falling back on alcohol when you were doing so well. I have done this many times, and the guilt & remorse is so horrible - it just is not worth it for a few moments of so-called relief.
Sharing your pain was a good idea, and please know that you have many people on your side, rooting for you to make it through this without caving. Please let us know how you're doing. We care about you.
