Slow down and simply do some deep breathing. You cannot fix all of these problems at once, and drinking will actually make them all worse - so your sole focus should be not picking up a drink right now. Coming here was a great idea, you could have made a lot worse choices. Make sure you aren't hungry, drink some water...you most likely need rest too so try and get some of that as well if you can. Tomorrow will be another day and you can tackle some of the other issues one at a time once you've taken care of yourself first.
