I agree with those who suggest the anxiety you're experiencing may be tied to acute alcohol dependence. Once you're able to stay away from alcohol for more than a week or so, most of the anxiety will likely abate.
Unfortunately, in the meantime, your anxiety is probably making you unnecessarily resistant to seeking help where it's most obvious. Your university has strict guidelines to protect the privacy of those who make use of its health services. The doctors there have undoubtedly seen cases of alcohol dependence before, and will not judge you nor violate your privacy. Go to the health center and tell them exactly what you've told us, without holding anything back. Do it ASAP. Every day that you continue to try to find relief in a bottle, you'll get worse instead of better, and you need to get to feeling better in time for your big presentation
