I understand that your at the bottom, but your not alone. There are millions of people around the world in the same problems as yourself.
The solution is money. I know its not popular, but I am one of those people who does believe money is everything because you can change your life with it.
The only solution is to reduce your outgoings and it seems you have done this, next you need to increase your income. You need a second, third maybe even a completely different job.
Time spent not drinking, is time when you can be working, even a hour here and an hour there. In time things will improve. Staying sober will be the best way to change your life and you will be the strongest amongst us, when you acheive it.
My advice to you is WORK, WORK WORK. Take your mind of your worries. Take any work you can find and fit it. Sleep when you can, eat when you can and forget the $4 bottle a wine to make you feel better, it wont help you. If it did, if it really did, we wouldnt be here now.
