Are you in the US? If so, mandatory insurance has been in effect for a couple of years now, and simply calling your local health department or even applying online can get your coverage. Also I would not be concerned about medication, rather the drinking.
Benzos are the first line of defense in withdraw to stop you from possibly dying from DT's. I also suffer from severe anxiety and they help me substantially to at least have some kind of quality to life.
It is common to be paranoid and afraid of medications, and simply turn back to the bottle, but in the end that is the worst thing you can do. Be honest with your docs, they are there to help.
